The Startup Therapy Couch™: Be actively managing your confidence!
It's easy to think of confidence as a binary personality trait: you either have it or you don't. In reality, confidence is a habit that can be learned, and it must be actively managed!
As entrepreneurs, actively managing your confidence requires figuring out the things, people, situations that make you feel confident, and then learning how to put your mind and body in that same state before doing something that you need confidence for, like pitching to investors, speaking to a group, or talking on the phone to a client or potential new client.
No matter how you get into a confident mindset, remember to practice doing it regularly. Hone that skill everyday so that when you need it, your confidence is right at your fingertips.
