I’m journaling nightly after each performance of Cabaret and one thing has occurred to me- though it should be obvious.
You must commit. To the action, to the line, to what your character is after. Commit.
The thing that stops this commitment is actually self doubt. And if self doubt stops commitment then it’s a self fulfilling prophecy.
Commit to the bit and when you feel like it won’t work- commit harder and don’t look back.
