I went to a seminar over the weekend. Kyle Cease's Evolving Out Loud. It was awesome, and if you have the chance to go, I highly recommend it. He talks about breaking through our fears and doing things we want to do in spite of feeling afraid. His message is that we all have a gift that the world is waiting for and needing, and if our fears and "Yeah, but..."s are getting in the way of us achieving our mission, then the world is missing out.
Anyways, it was good stuff for sure. If you ever get a chance to go see him, I'd recommend it.
