Embrace fear!
You’re always going to be afraid, and when you feel afraid and uncomfortable that means you need to do it... This famous theatre artist (forget their name) throws up before going on stage because they are fearful of performing, but they go on stage and perform anyways and do an outstanding job.
But, if you fail keep going because guess what, you got an outcome. Rather try and fail then not try at all, that’s the real failure.
