Think about what you truly want to be in life, not the normal "i want to be an astronaut" that we think about, but ask yourself who you want to become as a person. Once you figure out what you want to be, ask yourself "what is one small step i could take to bring myself closer to who i want to become" then take that step. Yes, it may be scary, it may be something you dont want to do, but its something to bring yourself closer to what you want to become.
