Our society will constantly scream at you that you are not:

young enough
thin enough
smooth enough
tall enough
smart enough
funny enough
pretty enough
exciting enough

and no matter how comfortable you feel in your own skin, every once in a while it's gonna break through and start chipping away at your brain, planting doubts and insecurities.

The trick is to find a balance or a really good shield of some sort

And a partner in crime who thinks you are all those things no matter what

Good Luck
