Don’t rest on prior accomplishments. That was yesterday and tomorrow doesn’t care about that.
So what if you were in great physical shape 5 years ago, you’re a fat slob now. That great year of work you had back in 2018, that was three years ago. Get over it and build new stuff.
Don’t believe the best or worst things people say about you. The best stuff gets you high on a figment of somebody’s imagination.
Measure your happiness against the effort you apply and the performance you have. Complacency is the enemy of success.
