If an idea is true, criticism will not destroy it, but strengthen it. - James Clear

Time spent working hard is often better spent identifying where the bottleneck is located.

Working hard on the wrong thing leads to frustration, not progress.

Many good opportunities are ruined for the dream of slightly better ones.

Would you have a more successful career if you had taken that other job or moved cities? Possibly. But your actual career will definitely suffer if you don't commit to doing it to the best of your ability.

Would you be 10% happier in a different relationship? Maybe. Maybe not. But you'll definitely be unhappy in the one you have if you spend all day thinking about what else is out there.

The surefire way to end up worse off is to agonize over unchosen options and fail to make the most of the one you selected. Every minute spent yearning for your unlived lives is a moment you can't invest in the one you actually have.

Choices matter, but so does your level of commitment.

Avoiding mistakes is an underrated way to improve. It's easier to fend off a bad day than achieve a perfect day. Rather than do your best, avoid your worst.
