It's dangerous to go alone!
Even if you are creating a game all by yourself, don't go alone on this journey. Find a fellow game developer to join you. You two don't need to work on the same project; the idea is to support each other: talk to your friend everyday (or at least a few days a week), explain what you're doing in your project, complain about that feature/bug that got you stuck for days, share that cool video/article you found the other day. The path will be easier and more enjoyable. Try it!
