He's underwent a one year transformation and documented his journey. Now that he's there, he's sharing his knowledge with others helping them also undergo a transformation. Way to go Flex. You can find him here on YouTube.

You don't need a degree to make a point or to teach something of value. Especially not in this age. Maybe back when no one could read and libraries didn't exist but now, you are seconds away from doctoral knowledge.
What's more, we are so hyper connected, we can easy get high quality advice from anywhere from down the street to the other side of the world.
Sure degrees are nice, but they are simply no longer a requirement to make a ruckus and to create art.
So Create Art.
Make a ruckus. Share your knowledge and wisdom.
I don't have a degree in being a husband nor a father. I learn more about being better in both everyday and apply the skills liberally.
You just imperfect yourself until to are better than good. That's what makes your extraordinary.
Sometimes you might fumble the ball. So do superstars in the NFL. Basically, give what you have and grow along the way.

Speak your wisdom. Create your art. Make your ruckus.
Way to go Flex!
