It can be hard to maintain a positive sense of self and faith that your dreams can come true when you’re overwhelmed with difficult circumstances. And it can be even harder when you’re surrounded by people who don’t believe in you, or who reinforce your negative opinion of yourself and your circumstances.

Perhaps no one understands this better than someone who is or has been in prison. They constantly deal with the profound loss of their freedom and the bad stigma society has placed on them. What’s more, they probably didn’t start out feeling very good about themselves to have committed the crimes that landed them in prison in the first place.

That’s where Sean Stephenson’s teaching come in. Stephenson, who is just under three-feet tall and was born with a rare condition that makes his bones fragile and confines him to a wheelchair, knows what it’s like to deal with severe limitation that can make one feel “imprisoned.” But he also broken free of the prison of his mind to live a fulfilled and happy life, and is now helping others to do the same.

Watch the inspiring video on the next page as Stephenson speaks to an audience of prisoners at Ironwood Prison — and teaches exactly how to break free from the prison of your mind.
