This is a thing.
You are not alone. Every person who starts something they think they might be passionate about has this feeling. This feeling is that you are going to conquer the world. You are going to get really good with it. Whatever your respective minds create in that thought, believe in it. Remember this feeling.
Now go. Create. Let the vision of others be your inspiration. This world that you are thinking about entering, the community that you are about to join, is one that you have so much to learn about.
