Every blogger wants to be an author. Every Instagrammer seeks to be a photographer. Every kid that plays FIFA wants to be Leo Messi.
If you're a writer, write. If you're a photographer, go out and capture. If you're a football player, play. Make constant mistakes, with good intentions. Everything is practice.
You don't need permission to make stuff and share it with the world. One of the greatest advantages of the Internet is the ability to share your work and get feedback. The edgier you are, the likelier you are to stand out and get noticed. You already have a Facebook profile, so you're already naked; no one is truly anonymous anymore.
The world doesn't want you to challenge it. It vows to impede your curiosity with short-sightedness. So imagine if you could just learn and do the work, staying open to new possibilities. One thing leads to the next if you're willing to use all the colors in the palette.
