Most of us think of transformation in terms of losing weight.
That makes sense being that more than half of us are overweight. But, some people are just the opposite. They struggle to put on weight. You need to remember that when an average weight is set, there are people above and as well as people below that number. This young guy showed a lot of courage to do this on his own and he should be proud of what he has achieved.
Don’t let age or size determine who you want to be. Just go out and be that person.
