Undecided Goal

Is it possible to achieve game developer by himself/herself?
I don't know if this kind of skill does make any sense because a lot of skills are needed to become a solo game developer. It's hard to think that I need to learn some other skills to achieve my goal, but the worst of it is that I don't know if this kind of career can make me happy. I love seeing games and playing games, so I decided to learn making games and achieving solo game development because I love games, guys. But sometimes I think of myself as "I'm just dreaming. That's impossible to achieve; I should give up." What do you think guys about my goal? Is it good and possible to do, or is it just a bunch of goals only? Let me know, and I hope you respect my questions because you are a developer also, so you know what you need to answer.
