Pardon my French, but…
Let that shit go, bro.
It’s a strange way of trying to be zen, maybe not necessarily Buddhist, but still it’s true.
Do you want to spend the rest of your life worrying? Letting fear, embarrassment, and paranoia take over your life with every trip on the sidewalk, Freudian word slip, or spilled cup of coffee? Which… if you’re a caffeine addict I guess is actually quite disastrous… but still… Would you rather worry? Or would you rather let the negativity roll off you like rain on a gore tex jacket and move on, happily looking for the sunshine through the clouds?
Some things we can’t change. Most things we can’t change, actually, but we can still be happy, if only refuse to let the pessimist inside us win.
