Just say "yes"?

Moments ago, I got a Facebook comment from a nearby filmmaker who has a Sundance-backed feature brewing. He says he could use my help with something --- presumably this feature with the pretty decent budget. How can I say "no"? I need to get something out there that has my name on it. I need to make some money. Simple, right?

I am currently doctoring a US/Bollywood screenplay, writing a family film and a short sci-fi political allegory. On top of all that, I recently dusted off a pet project, the treatment for a screenplay that I'd started last year and now think could be a viable project for me to produce --- much like "Aftermath", the script that was optioned to an L.A. producer last year, it is a grungy, low-budget real time piece.

The question is: How do I do it all?

There is one school of thought that says beginning screenwriters should not work for free or deferred pay because it sends the wrong message to producers who think they can walk all over us -- which, to some degree, is true. On the other hand, I have to start somewhere, get my name out there so that, maybe, someone will hire me.

So, I guess that's why I do it, say "yes" to everything, even if it kills me.

I have the Indian script due on 3/31 but it's going well. The family film is due 4/15 and it's going well. Will I ever get to the point where I can write one or two screenplays a year and be happy? If I do get to that point will I be happy or will I miss the days when I had to run around, chasing down gigs that might or might not pay, might or might not get made?

Or will I just get a real job?
