If you don't defend your team,
you shouldn't be leading one.

A title means nothing if your people feel unsafe.

Leadership is revealed when things get tough.

The best leaders protect their teams from toxicity that kills trust and motivation.

7 workplace issues great leaders guard against:

1. Unrealistic Expectations
Pushing for endless output leads to burnout.
Set ambitious but sustainable goals instead.

2. Micromanagement
Hovering over every detail kills creativity.
Empower people to own their work.

3. Blame Culture
Fear of mistakes shuts down innovation.
Fix problems, not people.

4. Unnecessary Distractions
Endless meetings wreck focus.
Protect deep work time.

5. Unclear Direction
Confusion leads to frustration and wasted effort.
Communicate clearly. Align expectations.

6. Office Politics
Drama tears teams apart.
Promote transparency and fairness.

7. Lack of Recognition
Feeling unseen kills engagement.
Celebrate wins, big and small.

The best leaders know that their job is to make great work possible.

Which of these resonates most with your experience?

A True Leader Protects You

When I led my first real project, half the team didn't really do anything...

A few people even disappeared when deadlines hit.

And two people – just two – kept the whole thing alive.

They stayed late.
They fixed what others broke.
They refused to let it fail.

We love to say “teamwork makes the dream work.”

It sounds nice.
It even rhymes.
But often it’s not true.

Here are the 3 types of people in a team:

1/ A few people carry the mission.

These are your DRIVERS.
They don’t wait for direction.
They just make it happen.
They treat every project like it has their name on it.

2. Most people just follow along

These are your PASSENGERS.
They get going once things are already moving.
They’re good people, just not self-starters.
They ride the momentum, but they rarely create it.

3. Some people pull it backwards.

These are your DRAINERS.
All talk. No output. Lots of excuses.
They slow progress in the name of “better alignment.”

What should you do with each of these?

Give your Drivers power and pay them very well.

Give your Passengers tasks that stretch them a bit.

And give your Drainers a mirror and a moment to decide whether they want to be on the team at all.

Which type are you...?

How to rescue a stuck team

You might be sabotaging your credibility without realising it.

Here are 8 myths still running rampant in most workplaces:
 
𝗠𝘆𝘁𝗵: Credibility comes from knowing all the answers.
↳ 𝗧𝗿𝘂𝘁𝗵: It comes from admitting when you don’t know and finding solutions.
 
𝗠𝘆𝘁𝗵: Being busy makes you look important.
↳ 𝗧𝗿𝘂𝘁𝗵: Results make you important.

𝗠𝘆𝘁𝗵: Speaking the most in meetings makes you influential.
↳ 𝗧𝗿𝘂𝘁𝗵: Thoughtful, well-timed insights carry real weight.
 
𝗠𝘆𝘁𝗵: Asking questions makes you look inexperienced.
↳ 𝗧𝗿𝘂𝘁𝗵: Smart questions show curiosity and critical thinking.
 
𝗠𝘆𝘁𝗵: Taking sole credit boosts your reputation.
↳ 𝗧𝗿𝘂𝘁𝗵: Sharing credit builds trust and leadership presence.
 
𝗠𝘆𝘁𝗵: Staying quiet avoids conflict and protects credibility.
↳ 𝗧𝗿𝘂𝘁𝗵: Addressing issues constructively builds integrity and influence.
 
𝗠𝘆𝘁𝗵: Showing emotions makes you look weak.
↳ 𝗧𝗿𝘂𝘁𝗵: Authenticity fosters stronger relationships.
 
𝗠𝘆𝘁𝗵: Keeping to yourself makes you look focused.
↳ 𝗧𝗿𝘂𝘁𝗵: Engaging with colleagues enhances trust and collaboration.
 
The takeaway?

Credibility isn’t about looking smart, busy, or perfect.
👉 It’s about trust, consistency, and impact.

🔔 Follow me (Mostyn Wilson) for frameworks to build credibility and career momentum.

Infographic titled “8 Myths About Credibility at Work.” It lists eight common workplace misconceptions and their truths, each in paired blocks. Examples: “Myth: Credibility comes from knowing all the answers. Truth: It comes from admitting when you don’t know and finding solutions.” Other myths cover busyness, speaking too much, avoiding questions, taking credit, staying quiet, hiding emotions, and isolating yourself. The design uses bold headings and clear typography for readability. The visual reinforces the takeaway: credibility is built on trust, humility, collaboration, and authenticity — not perfection or busyness.

The longer you wait to feel ready...
The more you train your brain that doubt means “don’t”.

Your future self will never thank you for waiting.
 
They’ll thank you for starting.

And you’ll never feel completely ready.
 
Not for your first bold move.
Not for your next big role.
Not for the thing you actually want.
 
Most of us wait for the right moment.
 
More skills.
More experience.
More confidence.
 
But  that moment never arrives.
 
Here’s what I’ve learned from every leap I took before I felt ready:

→ The skills came after I started
→ My confidence grew with every step
→ The right people showed up once I was in motion
 
You don’t become ready by thinking.
You become ready by doing.
 
Top performers don’t wait for permission.
They act before they’re certain.
They grow into the roles they want.
 
Because action creates the confidence you’re waiting for.
 
Which area in your life needs less waiting, more starting?

We’re all facing a change marathon. But how can we be ‘change fit’ if we don’t workout?! 

Like it or not, you and your org can’t be change potatoes. [Insert long list of change here, must mention AI]. Perhaps you’re experiencing symptoms like: 
- Burnout and stress
- Change fatigue and resistance 
- Lack of inspiration and engagement

The good news is that we all can be change bunnies. Phew. 

Our change fit model and philosophy isn’t just backed up by research, we’ve put it into practice. I was often burnt out on the inside while seemingly successful on the outside during my corporate career. I learnt how to reignite my own inner flame. And I’ve made a big switch up of my game from Chief Risk Officer to Playfilled co-founder.

Regardless of the change, the fundamentals are the same; we need to keep our change core strong:
- Muscle: our creativity for new pathways
- Fuel: our wellbeing for performance
- Motion: our connectivity to people and purpose to enable progress 

And it is possible to enjoy getting off the change couch together. Happy high performance is what Playfilled helps people unlock. 

Our change fit clubs help ignite org change and activate your inner change bunny. Pilots showed that our 12-min virtual, creative speed networking - 'change HIIT' - delivered up to 20% uplift in mood and energy and got a 95% positive experience rating for pioneers from global tech, financial and professional services firms. 

And yes, I’m continually doing change training too. Check out how I (un)seriously switched up my social media game with my Cat Gif Challenge ⬇️
