The worst part of working in SQL? Waiting for your query to run.

Here are 9 tips for optimizing your SQL queries 

- Reduce Unnecessary Data Processing

Delay using ORDER BY until the final SELECT statement. Subqueries and CTEs usually don�t need ordering.

Use DISTINCT sparingly. It can be computationally expensive, especially on large datasets.

Opt for UNION ALL instead of UNION when duplicates are acceptable or unlikely.

SELECT only the specific columns you need instead of using SELECT *.

- Take Advantage of Indexes on Your Tables

Filter on the index key whenever possible to minimise the data size processed.

Limit the use of OR conditions, as they can lead to inefficient full table scans.

Avoid using functions in WHERE clauses, as they can interfere with indexing.

- Reduce Cardinality of JOINS

Use a CTE or subquery to filter and reduce table sizes before performing a JOIN.

Apply filter conditions in the ON clause rather than the WHERE clause to reduce rows before the JOIN operation.

There’s a moment most people don’t talk about.

It’s when you’re doing the hard work…

Showing up.
Practicing.
Learning.
Trying again.

Consistency rarely feels exciting.
But it compounds over time.

Sometimes all you have is your own commitment.

No validation.
No reassurance.
Just the choice to keep going.

Today is Friday.

Take a moment to clap for someone who’s been working hard this week — whatever that looks like.

Help them head into the weekend feeling seen and appreciated.

Sometimes being seen matters more than being celebrated.

Who are you clapping for today?

Not every squirrel deserves a chase. 🐿️

Leadership isn’t about eliminating squirrels.
It’s about managing them.

A squirrel is a shiny, urgent-looking distraction that pulls attention away from priorities.

The result?
Unfinished work, wasted resources, and lost momentum.

Before you know it, you’re chasing squirrels — and the infestation has taken over.

Here’s how to get focus back:

✅ Anchor the team to goals and the roadmap

↳ Clear objectives and a shared roadmap reduce distraction and align effort.

✅ Make priorities visible and set a WIP (Work in Progress) limit

↳ WIP limits ensure work is finished before new work starts — reducing half-done efforts and context switching.

✅ Design the environment for focus

↳ Set norms for collaboration versus deep-focus time. 
↳ Reduce noise through fewer notifications and intentional communication windows.

✅ Normalize “not right now”

↳ Visible boundary-setting from leaders makes disciplined prioritization safe across the team.

✅ Create an idea backlog

↳ Capture new ideas for later review instead of letting them hijack today’s priorities.

✅ Establish a clear operating rhythm

↳ Define where new work enters the system and how priorities are reviewed. 
↳ Route new requests into that forum to prevent ad-hoc disruption.

The goal isn’t to eliminate squirrels.
It’s to stop letting them dictate the work.

Having trouble making change stick in your organization?

According to John Kotter, 60–90% of change efforts fail—not because of bad ideas, but because execution misses one (or more) of these 8 critical steps.

Here’s a breakdown of Kotter’s 8-Step Change Model that every leader should have pinned to their wall 👇

1️⃣ Create a Sense of Urgency
↳ Make the case for change by tying it to real risks, timely opportunities, and a mission that motivates immediate action.

2️⃣ Build a Guiding Coalition
↳ Change isn’t a solo mission. Build a team of trusted, credible leaders who will champion and drive the effort forward.

3️⃣ Form a Strategic Vision & Initiatives
↳ Clarify the future state. Connect the vision to clear, actionable steps your people can rally behind.

4️⃣ Enlist a Volunteer Army
↳ Inspire broad participation by showing people how their contributions matter. Celebrate engagement at every level.

5️⃣ Remove Barriers
↳ Eliminate blockers—whether they’re outdated systems, siloed structures, or limiting mindsets.

6️⃣ Generate Short-Term Wins
↳ Early wins build momentum. Celebrate them publicly to reinforce belief in the mission.

7️⃣ Sustain Acceleration
↳ Keep up the pace. Use wins to expand change, train others, and go after deeper challenges.

8️⃣ Institute Change
↳ Make transformation stick. Embed new behaviors in your systems, culture, and leadership practices.

AI doesn’t forget.

Organizations are feeding contracts, support tickets, and internal documents into AI systems — often without removing sensitive data first.

Once that data trains a model, it’s embedded. You can’t undo it.

That creates real business risk.

And if you’ve ever redacted documents at scale, you know how labor-intensive and high-risk that work can be.

I’ve started recommending Redactable® as a quality solution to my clients.

Redactable® replaces manual redaction with automated detection and permanent removal — including hidden metadata.

Here is what makes this solution great:

✔️ Automated detection:
Identifies 40+ sensitive data categories across unstructured docs, tickets, and logs.

✔️ Permanent removal:
Strips text and metadata so models never see sensitive information.

✔️ Compliance certificates:
Generates audit-ready redaction certificates.

✔️ Delivers 98% time savings for your team:
Reduces manual redaction effort and risk of error.

✔️ Flexible integration:
Works via API for pipelines or direct upload of selected documents.

Want to try before you buy?
You can try Redactable® for free by redacting up to three documents.

Most organizations are still planning for stability.

But we’re not in that world anymore.

We’re living through the most volatile decade on record — shaped by geopolitical tensions, climate changes, economic swings, and rapid technological disruption.

Certainty is no longer a given.

Organizations clinging to static plans are being tested — and many are failing.

Volatility is exposing a critical flaw —

Too many organizations are planning for stability when they should be strategizing for change.

Strategy vs. Planning: What’s the Difference?

Strategy:
✅ Defines direction, even when the path keeps shifting

✅Aligns teams around outcomes and goals — not step-by-step activities

✅Builds on synergy between means, money, market, and meaning

✅Encourages check-and-adjust operating models— built for dynamic environments

Planning:
❌ Assumes a defined start and end state

❌ Focuses too heavily on task-level detail, limiting adaptability

❌ Works in static environments with minimal change

❌ Struggles to hold up in volatile environments.

In a world of constant disruption, the best plan won’t win.

It’s the organizations that can rally their teams around strategy — and embed systems to share information, adapt quickly, and stay aligned.

Is your organization struggling to deliver results in today’s volatile environment? 

👉 Maybe it is time to shift your operating mindset and align your organization to a strategy.

Why do clients choose you?

Because they trust you.

Research shows it takes 7 meaningful touchpoints before a potential client trusts you.

That means your success doesn’t just depend on being good at what you do—it depends on how effectively you create opportunities for people to engage with your expertise and see your value.

This was a recurring theme in the monetization panel I participated in yesterday: trust is built before the sale ever happens—through repeated, intentional touchpoints.

Here are 7 powerful ways to build trust with potential clients:

✅ Referrals
Still the #1 most trusted source of new business. According to Nielsen’s Global Trust in Advertising research, referrals from people you know are the most trusted source of influence.

✅ Public Speaking
Share your expertise through keynotes, workshops, or webinars. It builds authority and signals you’re a trusted voice in your industry.

✅ Newsletters
Consistently deliver value through insights, tips, and thought leadership. A newsletter nurtures your audience over time.

✅ Social Media
Share written and video content that showcases your knowledge, process, and personality. Consistency builds credibility.

✅ Case Studies
Turn your wins into stories. Case studies show how you solve real problems—and help clients envision working with you.

✅ Strategic Networking
Get in the room. Attend events where your ideal clients, collaborators, or referral partners spend time.

✅ Endorsements & Testimonials
Don’t let happy clients stay quiet—ask for testimonials and LinkedIn endorsements. Ask right after a clear win or milestone.

Which one has worked best for you?
