There are many ways to express yourself and your abilities. The first step in expressing yourself is stepping out of your comfort zone. Stepping out of your comfort zone can be done by doing things you never thought you could, or would do. Trying new foods, games, styles, etc can help. From my personal experience, it is in every way worth it. You will reap benefits such as new friends, that can relate to you and your personal life.
In conclusion, stepping out of the box is something that you should do.
