Mastery of Oneself

Tiny Thoughts

Consistency compounds while occasional brilliance fades.


You don’t need more time. You need more focus.

Time isn’t the constraint. Your choices are.


Great outcomes aren’t built on great days, but on consistent ones.

You can’t just count the days when it’s easy. Each day moves you closer to the goal. No day is a hero; no day is a villain.

Perfect days don’t compound. Consistent ones do.

Insights

Steven Bartlett on doing things to prove yourself right:

“Everything you do – with or without an audience – provides evidence to you about who you are and what you’re capable of.”


Leonardo da Vinci on self-mastery:

“One can have no smaller or greater mastery than mastery of oneself; you will never have a greater or lesser dominion than that over yourself; the height of your success is gauged by your self-mastery, the depth of your failure by your self-abandonment. Those who cannot establish dominion over themselves will have no dominion over others.”


Toni Morrison on beauty:

“I think of beauty as an absolute necessity. I don’t think it’s a privilege or an indulgence, it’s not even a quest. I think it’s almost like knowledge, which is to say, it’s what we were born for. I think finding, incorporating and then representing beauty is what humans do. With or without authorities telling us what it is, I think it would exist in any case.

The startle and the wonder of being in this place. This overwhelming beauty—some of it is natural, some of it is man-made, some of it is casual, some of it is a mere glance—is an absolute necessity. I don’t think we can do without it any more than we can do without dreams or oxygen.”

Mental Models

A mental model is a simplified explanation of how something works.

V3 | Systems | Churn

“Churn is the silent killer of businesses. It’s the slow leak, the constant drip of customers slipping away, of users drifting off to find something new. The attrition eats away at your growth, forcing you to keep running to stay in place.

The thing about churn is that it’s often hidden. It’s not like a crisis that grabs your attention. It’s a slow, quiet process that happens in the background. Churn can present opportunity. Like a snake shedding its skin, replacing components of a system is a natural part to keeping it healthy. New parts can improve functionality.

But here’s what’s counterintuitive: some churn is healthy. New employees bring new ideas; new customers bring new opportunities. Replacing what is worn out creates new opportunities. Some churn is inevitable. Too much can kill you.”

Reading

Most people think success comes from following the rules. James Dyson proves the opposite.

In Against the Odds, he describes how being a misfit—stubborn, opinionated, unwilling to conform—wasn’t a weakness but his greatest advantage.

“I have been a misfit throughout my professional life, and that seems to have worked to my advantage. Misfits are not born or made; they make themselves. And a stubborn opinionated child, desperate to be different and to be right, encounters only smaller refractions of the problems he will always experience. And he carries the weight of that dislocation for ever.”

+ Members can access all 118 highlights from Against the Odds and hundreds of other books in the repository.

Thanks for reading,
