I personally spent the best part of 6 years chasing the same path that you seem to be on....and came very close to packing the whole thing in, including my support of the club, due to the frustrations of not actually achieving very much (in terms of getting support from others).
It wasn't until I refocused....thanks to people telling me the same thing I'm saying to you....that I found a task that allowed me achieve something tangible through my contribution, and something that I (mostly) enjoy and get a great deal of personal satisfaction from.
I still champion the idea of a lot people doing a little instead of few people doing a lot...it's just no longer the primary focus. And the thing is, more people have come forward to offer help and get involved in the past 2 years than I ever saw in the 6 years prior to that.
I'm not the only person that's been in the above position and had those experiences, but I can only speak for myself. For all I know, you may be the person to get a different result and if you truly believe you can, then go for it. Being the stubborn, opinionated SOB that I am, it's probably what I would do (and did for years)
