Authenticity!!! It does matter.
"Do not try to dance better than anyone else, only try to dance better than yourself." Mikhail Baryshnikov. And always remember comparison is lethal. JUST DO YOU.
Consider your own imperfections and set out to remedy them.
The greatest opportunity is who you are. Do not despise yourself! Find a place to stand and from that place remake the world. You are only going to be as good as the things and people you surround yourself with.
Do not throw yourself away. Keep all your passions with you.
Go on and author your story.
Stop expecting that things will go wrong, remember that everything has Gods fingerprints on it.
Therefore, silence your greatest critic - YOU. And that's how you will dent the universe positively.
