Ok I'll give you a longer answer. Right now you're throwing strikes, you're getting batters out and you're healthy. At 13 years old, You are at the crossroads. You either keep doing what your doing and enjoy playing baseball for the rest of your life, evolving as you mature and become older and stronger OR, you can start thinking about baseball in a more competitive way, trying to be the best at the highest level you can reach. This also means you will need to start working out, practice hard and spend a lot of time on the field. There really isn't any in between. The guys you see on TV chose #2 the men you see playing at your local field chose #1 . Both are very happy.
