Oh Boy, This Is A Big One

Recently I wrote something about making choices.  Little did I know that I would be facing one of the biggest choices, or decisions if you want to put it that way, than I am now.  We’re talking on a scale of one through ten this is a hundred.  Yeah, that big.
You all know I’m a writer.  That’s what I do.  I recently offered a little help with a movie and OK it wasn’t no big deal.  I did it, I don’t have any regrets, it’s all good.
Then someone did something way outside my comfort zone.  I won’t mention names here or amounts, but someone offered me a nice little sum to turn one of my books into a movie.  Yes, you read that right, a movie.
To be honest with you I really just didn’t see it being feasible.  The kind of money you need to make a movie is high, then you have a writer who can only be known as unknown pretty much.  Why the hell would anyone want to go see a movie written by someone they haven’t of heard from Adam.  I then realized that people do it all the time.  Someone comes up with an idea, writes a script, and bang you have a movie that people go see.  To me it makes more sense to read the book or at least heard of a book before you invest your time in seeing a movie from some unknown person or persons.
I decided to ask someone with experience with this sort of thing, making movies that is, and all of a sudden, he’s giving me all kinds of reason why I should and ways to do it.  What do I do?  I would love it if I got more comments about what I write on my website, but this is one time when you guys could really help me out.  What do you think I should do?  Should I pursue this or not?
This also isn’t a matter of someone trying to buy the movie rights to my books so I would have total control.  It would still be mine with me having finale word on everything.  We might be talking every writer’s dream, but I’m scared out of my wits.  I write.  That’s what I love to do.  I’m not a movie maker and I know absolutely nothing about it.  I write for me and hope others will see in it what I do, but when you make a movie it changes everything.  There will be people depending on this movie doing good and if it doesn’t no matter who is at fault for that I feel that it comes back on me.
So, come on people leave a comment and let me know what you think.  It could go a long way to help me make up my mind.
