Fear can be a good and bad motivator.
Sometimes when your back is to the wall, fear will kick you into action.
The problem is however many people today let fear guide their choices. I might suggest you try the opposite like George Costanza on Seinfeld. Instead of spending the day making choices to avoid pain, try making them to seek pleasure or maybe even to head right into the eye of your fear.
I remember the first time I wanted to film a blog video. I was SO scared. Scared of judgement. ridicule, criticism and more. Then I realized that you get way more kudos than criticism for putting yourself out there. The best part is the critics tend to be dealing with their own fears, and you recognize that if they do show up.
Don’t be so damn scared. You are safe, start making choices like someone who has choices.
