It's not you waiting that will give you the confidence you want, it's you acting. It's by doing the things that scare you that you realize you can get confident. It's not the other way around.
I love how Mastin Kipp puts it:
If you're not in mortal danger, fear is a compass showing you where to go.
You don't have to of course, it's always up to you. But if you want to live the life of your dreams, you've got to dare to be the person you need to be to live that dream. If the life of your dreams is inside your comfort zone then stay, if it's something else, get going. Move, and try, and dare, and you'll notice with time, what once scared you is now easy-peasy and what was once totally in your risk zone is now only a light stretch. Act how you want to feel and the confidence is just an added bonus.
With all my love,
