I couldn’t put it any more succinctly than Seth Godin:-
“Alas, this is the wrong question.
The only way to get rid of the fear is to stop doing things that might not work, to stop putting yourself out there, to stop doing work that matters.
No, the right question is, “How do I dance with the fear?”
Fear is not the enemy. Paralysis is the enemy.”
I would add from Wendy Backlund –
“Only daring speculation can lead you further. Worry is dreaming with the enemy, but daring speculation is dreaming with God.” And, “Any time we live out of fear, we are living out of a poverty spirit.”
