It's so common a phenomenon--hesitating to make a decision, to commit to a direction for fear of what you'll miss or what you'll lose. I remember thinking this as a kid--that I was wasting my life, that somewhere, somehow a place existed where I could be effortlessly funny/brave/clever/talented/etc. An early, pre-millennial FoMO--it may sport a new text-y acronym, but it's nothing new.
But holy cats will that mentality ever drive you nuts--the only result possible is either an over-committing exhaustion of resources or committing to nothing at all, drowning in that pit in your stomach that knows you should be doing *something* but with no clear idea about which something to choose.
Well, here's the thing. Put your hand on your heart. Breathe there and push the choice into your chest. How do you feel? How do you REALLY feel? Then commit to that feeling and communicate your choice--clearly with no hesitation and no apology.
Our minds are crafty survivalists and skilled liars. It's not their fault--we've trained them well. But for the heart, truth is the only currency and there is no uncertainty, only knowing.
