It can be scary to try something new. What if you mess up? What if it doesn't go as planned?
No matter what happens, there is one way to gain value from any situation. Reflection.
Reflection is how you get the most out of any experience. The insight you gain from reflection can be used for anticipation. Mess up today, reflect on it, and you are more likely to be able to anticipate what will happen in the future.
Exerpeince isn't worth much unless it is ran through the wash of reflection.
