There's no such thing as fear of success... it's the fear of failing once you succeed!
Fear sucks. It literally sucks all our ambition, confidence and trust into a black hole we come to know as our self-esteem.
I was once grocery shopping, pleasantly minding my own business when all of a sudden, I noticed an acquaintance standing at the end of the aisle, pondering spaghetti sauces. How intrusive... this is my supermarket! All at once, I found myself darting down the adjacent aisle, hoping not to have been discovered, just to preserve a few more moments of domestic anonymity.
And all the while, an inner bully taunted me with shudders of rejection and intimate panic at the very notion that I might be 'outed' in an unscripted vulnerable moment of a real life encounter!
As a clinician I was never clear what self-esteem really meant so I looked it up in my Pocket Oxford and it became clear all at once; derived from the Latin verb, aestimare, it means to estimate or compare. Who knew?
