 Put yourself into situations that expose you to things that are outside of your comfort zone. This is very good for us. I know at the time it doesn't feel like it, but it's very good for us to get around people and places and things and ideas that you spend most of your life avoiding. And you can do this online to physically be in a place where you physically feel embarrassed, though that can be good too, because embarrassment is overrated as a reason for not to do something. Embarrassment won't kill you.
