A super cool lesson that a coach taught me was as long as you try, you can do it. He use to make us swim across the pool, which is 25 yards long, without coming up for air. I always thought that I wouldn't be able to do it. I was actually able to do it. It took me most of my 6th grade swim season, but I was finally able to do it. I use his lesson now in everything I do. I always try and I usually can accomplish whatever I try for.
