Putting yourself in places where you don't feel like you fit is a truth I've learned repeatedly: good things happen.
You can see those rooms all around you, but you're afraid of being caught, so you don't go in.
I changed my life when I learned that everyone could contribute something valuable to a talk. Your experiences and how you see the world are unique and might give someone else a new perspective.
That feeling of not knowing what to do, being afraid, and being uncomfortable is often a sign of change.
