I have self-doubt, I have insecurity, I have fear of failure.
I have nights show up at the arena and I'm like 'my back hurts, my feet hurt, my knees hurt. I don't have it. I just want to chill.'
We all have self-doubt. You don't deny it, but you also don't capitulate to it. You embrace it.
-Kobe Bryant-
Even Kobe can't immune from self-doubt. Next time when you have self-doubt, think about the Black Mamba's mentality, instead of fear about it, embrace it, and be a better person today than you were yesterday.
