The only limits are the ones you place on yourself.

One of my life goals (I have a few of them) is to dunk. I'm 5'9" and I barely have average hops...at the moment. That's right, I'm going to dunk. What's stopping me? Nothing. I already have over half the distance covered with my height, let's just add some hops and I'm good. I came to this decision about a week ago that I am going to do this. The time is now. Here is a video of one of my favorite competitors in the NBA, 5'7" Nate Robinson doing his thing as inspiration. Let's go!!!
