I think everybody has a moment in their career where you have to test whether it was right or wrong. We've all been there. I've looked back at performances of my own, where only you know if it is something you want to repeat. As long as you know when it's not right that you don't repeat it all the time.
Jessie JI think the best way to have confidence is not to allow everyone else's insecurities to be your own.
