"When I get sad, I stop being sad and be awesome instead. True story"
This is one of my favorite quotes by Barney Stinson (or any character). The truth is that there is actual value in that saying. There are a lot of things that we wish we could do, but can't. We were not gifted with that talent. What most of us do, though, is complain/sulk instead of actually doing something about it.

You can see how he continued to progress through hard work (he gets more and more jacked). Pretty impressive kid, I must say.
