He has not had an easy go of things (to put it lightly) and I couldn't be more proud of him for making some positive changes in his life, including going back to school to get his grade 12 diploma!
I found this Dr. Suess quote, which I thought was a good fit:
"You have brains in your head, you have feet in your shoes
You can steer yourself any direction you choose.
You're on your own and you know what you know,
You are the guy who'll decide where to go."
Way to go G, we are all so proud of you!!!
