I relate to your need to do something bigger than yourself to define you not as a wannabe, but as someone of some relevancy. The thing is that not even people who aren't on the spectrum can shake being ordinary. You might choose not to believe this and I am a walking proof of why you shouldn't believe it since I am not famous or successful the way you seem to define it, but one thing is for certain, if you can be good at something, regardless of how bigger than yourself it is or not, you don't need more money, or more gear, or a wife to reassure you. You, however, do need continuity, dedication, persistence, passion, creativity, time, ability to adapt to changes, being resourceful and doing something that feels true and very important to you. Even if you had the money, the gear, and the wife, success would be elusive if you lacked these intrinsic motivations. This might sound easier said and done, but it isn't. That's why not everyone is successful, even those with the money, gear and spouses...
I had spent a lifetime longing to do something bigger than myself, then all the pieces felt apart and I was diagnosed with Asperger. I realized that doing something that isn't true/important to one-self in order to be that what ones defines as success is a guarantee that one will never be motivated enough to do what it takes.
So, if this project is true/important to you and you can muster the energy and will to do continuity, dedication, persistence, passion, creativity, time, ability to adapt to changes, being resourceful, you will not have to kill yourself.
