Self-doubt will happen. It’s a natural part of doing something new.
Living a life without self-doubt means that you’re not trying anything new (or you’re over-confident).
If you haven’t ever done something before, you can’t be 100% sure that it’s going to work because you don’t have the personal experience. It’s impossible to know how it’s going to go.
The natural self-doubt that kicks in in these moments isn’t to be feared or worried about. It is a useful mechanism that can be used to safeguard yourself against potential failures.
Self-doubt is an intelligent response to doing something new.
Quitting, on the other hand, is often an emotional response to self-doubt.
