You can’t be great at everything, so choose what you’re fine being average at. That’s strategy, not weakness.

Excellence is expensive and the budget is fixed. Trying to be strong everywhere spreads the same hours thinner and produces a uniform mediocrity nobody actually chose. Deciding in advance where average is acceptable is what frees up the concentration that being genuinely good at one thing requires.

Write down the two things you want to be excellent at this year, then name three you will deliberately do to a decent standard and no further. Say it out loud so you stop feeling guilty about them. Guilt is what keeps people paying for things they never decided to buy.
