Just F'in Do It!
Ok, you really know what you want to do. You really do. So now that you know, just F'in do it. No one is going to fault you for trying. Actually, when you do fail, please call me and we can celebrate our failures together.
You are smart, you have the resources and you have the passion! Now just F'in do it!
I leave you with two quotes:
"There is but one failure in life and that is the failure to try. The greatest failure in life is the unwillingness to play your highest game and walk toward the places that frighten you"
"Before Columbus all previous adventurers sailed close to the shore, within sight of the land. That was the accepted way to sail. Columbus dared to be different. He refused to do what all others had done. He took a risk: he sailed perpendicular to the shore - straight out to sea. And because he let go of the known and had the bravery to sail out into the unknown, he became one of our greatest heroes"
