Remember, you are comparing yourself to everyone else's highlight reel.
You know your struggle, but you don't see theirs.
You are likely as good as them, maybe even better, but awareness of your flaws holds you back.
Be aware of those flaws, but know that they aren't always seen by everyone else.
Someone thinks you're cool... and you don't even know it.
It took me a VERY long time to acquire this knowledge...
Apply it liberally to make life better.
