Fantastic piece. The best three listicle I've seen on Medium so far.
A teacher of mine once asked: "What's wrong with being uncomfortable?"
The biggest change came for me after I transversed extreme fear (and there was no choice but to confront it and pass through it), extreme discomforted to the point of feeling insane. I got through it, got comfortable, dipped back into insanity, got comfortable, got fired.
I guess three Xs a charm Then I made the choice 44 years ago to attend a Spiritual (Gurdjieff) School and everything after that fell into place and wow. I've been on fire since then...
