There's huge upside to letting our guard down. My friend John once told me that he's never had someone share as much of their inner, emotional experience as I have with him. That's either a compliment or a plea for me to shut up, lol.
But having relationships in which we can share that interiority is vital. I'm not suggesting we tattoo any insecurity on our forehead, but I am saying that we should treat these special relationships as the gold that they are.
Real connection comes from sharing more than merely the highlights. If we let our closest friends see our incomplete selves, we share hope for betterment while providing insight into another human being who's (also) just trying to figure things out.
Lets share the stuff that shows we're unsure.
It'll help us all realize that we're not the only ones wondering what the hell is going on.
