During a paid performance, the flying trapeze artist who flinches before she leaps is the flying trapeze artist who ends up breaking a leg (not in the good, show business way).
The way to avoid the hesitating flinch is… trust (duh, Josh).
The way to build the trust is rehearsal. Hundreds if not thousands of attempts to leap off of boards into the arms of a partner or the bar of a trapeze, several stories above the ground with a net underneath.
Back to trust. Know that the infrastructure you set up for yourself and the weeks you spent on rehearsal and preparation are good enough. Trust that your muscle memory is strong and the neuropaths within your brain are prepared for numerous outcomes.
Don’t flinch… go all in. Put away the technique from rehearsal and act in the present (not the future of “what might be” or the past of “what was”).
