Your field guide

Doubt doesn’t go away when you achieve things. When it shows up, name it, then reach for the right tool.

The Doubt Decoder: name which doubt is talking
DoubtSounds likeDo this now
Comparison“Am I keeping up?”Mute social apps for an hour. Spend ten minutes listing what you’re proud of.
Perfectionism“It’s not good enough yet.”Send the draft as it is, or tell someone when they’ll see it.
Hesitation“What if it isn’t big enough?”Write “I want to ___.” Don’t plan it. Say it to one person.
Worthiness“Do I deserve this?”Write three things true about you that no title or opinion can take away.
Capacity“Can I handle this?”Set a ten-minute timer on the thing you’ve put off. Start, don’t finish.
Chair the board: ten minutes before any big decision

1. One honest sentence: “I’m avoiding ___ because ___.”

2. Give each one a line. Mouse: what am I worried about? Lion: what’s the next right move? Clown: what’s the lighter way through? Elephant: what matters long term?

3. The chair decides: “I hear all of you. Here’s what we’re doing.”

4. Take the next step within 24 hours.

5. Close the loop: what did I fear, what happened, what did it prove?

Courage habits: pick one a day

The first move. Initiate instead of waiting.

One hard thing. Do the task you’re resisting first.

A small boundary. Decline one thing. Protect your energy.

A visible share. Post, pitch or present the thing.

The reset. Each night, name one brave thing you did.

Your move in the next 48 hours

Name one brave thing you’ll do and who’ll hold you to it. Then send it to them. A commitment someone else knows about is far harder to dodge.

About the author

Luke Tobin

Luke Tobin is a three-time exited founder, multi-award-winning entrepreneur, and a highly sought-after voice on leadership, performance, and self-doubt. He scaled his last business, Digital Ethos, into one of the UK’s fastest-growing digital marketing agencies before leading it to a large multimillion-pound exit, a track record that earned him the Great British Entrepreneur Award in 2020.

He is now the founder of Unusual Group, which acquires minority stakes in marketing agencies, creative firms, and tech companies serving the creative industry. Alongside this, Luke runs Tobin Capital, investing in future-focused ventures across female-led brands, space, sustainability, deep tech, and biotech. He also owns Succeed, an M&A brokerage that helps founders navigate business sales.

Luke’s writing, newsletter, and social content reach tens of millions of people every month, and he has supported thousands of founders through the emotional and strategic weight of scaling and exiting high-value businesses. His work blends lived experience with performance psychology, showing readers how to turn self-doubt into strength, confidence and success.

The Power of Self-Doubt is Luke’s first book: a practical and deeply personal guide to harnessing doubt for anyone ready to grow into who they’re meant to become.
