You have power in this world. No matter who you are, how old you are, your gender, race, anything. Your thoughts have weight to them.
I hope you turn your thoughts into words one day, written with a pen or spoken from your mouth, because your words can move mountains.
Use your power for good. Every step you take will lead you somewhere, so make your steps count for something.
Our world is ruled by fear, the fear of failure, of not being heard, of being mocked. Don't let this fear control you because the power of your words is stronger than any fear that can be imposed on you.
In the end, even if you make mistakes, it's your decision whether or not that mistake becomes a failure. You can either accept failure, or dust yourself off and keep on thinking.
