Selbstzweifel – Self-Doubt
A couple of months ago I was watching a documentary in which the conductor Hossein Pishkar appeared. At one point he said …
Ich zweifle ständig und andauernd an mir. Selbstzweifel. Immer wieder. Nur beim Machen, da darf man keine haben!
… which translates into something like …
I keep doubting myself constantly. Self-doubt. Again and again. Only when acting, you must not have any!
I think if you decide to act and to do/make something you have to forget this constant self-doubt. It would block you and you can question yourself afterwards again (which you will). In the moment, just go with it. Give 100% and be confident.
