It’s easy to be confident when doing something you have some expertise in.
The difficult thing is to be confident when you are vulnerable.
Many of the great advances in the world have come about because of people being confident enough that they were willing to fail, willing to take chances and willing to look bad.
Anyone can be confident when doing things they do well, the challenge is being confident when there is uncertainty and knowing that you might embarrass yourself.
Be confident and have a great day!
