“I don’t know why I bother”
There are days where after some attempted damage control and immediate failure, I say to myself "I don't know why I even bother".
My fifth thought is the one that is worth listening to. "It was worth it." In the end, what truly matters is that you tried. Not that you failed in trying.
If you apply that logic to everything else in life, you might just get ahead.
Do not fear rejection, do not fear failure. Your brain is powerful, magical, even. Wipe the programming that you grew up with that causes you to stagnate as a person.
Become who you want to be. Pick yourself up and try again.
