What are you afraid of?
That you aren’t good enough?
You don’t know what you’re talking about?
You won’t be respected?
You won’t be heard?
You’ll be ignored?
Or maybe it’s that you’re afraid to everything you learned was wrong, and now you need to learn something new, go in a different direction and figure out what you should be doing.
That’s why they call it a community – they are there to push you and make you better – not pat you on the back (a community will do this when they see you pushing yourself, but not for the sake of doing it – big difference).
