I know the time commitment is a great one when it comes to writing. I know that such a time commitment is worth it when you enjoy it. I just think that in order to make such a commitment practical you must try to make money from it.
And
there, are the struggles of the Writer.
Practicality rarely comes from what you love. It's a test of time. It's your ability to gain the necessary standard that would lead to somebody purchasing your script. It's living, and learning the craft to tell an interesting, entertaining story that is adaptable to screen.
You won't sell a script on your first time out. Unless you've seen your material come to life. You've seen how you have to adapt, on how what's on the page can/cannot transfer to screen, you'll be very, very lucky to gain a purchase. A Director will, occassionaly, if the idea is really what he is after, happily take the script and do all of the work. But's it's not likely. We have to do everything we can. Everything that will give that Director, Prodco etc the BEST chance of SEEING our vision. If he can't see that vision on screen. It's over. That's our job.
It's a process.
Learn to
tell a story. (We all have ideas, it's making them entertaining that is the art)
Learn to craft a "spec" script. No exceptions.
The practicalities within the learning process are few. It depends on the person.
Can you last what is a long, long process without a job? Without earning an income?
It's not practical. You'll be frustrated. You'll arrive home tired. You want to write.
It's a balancing act.
If doing what we love was easy, everybody would do it.
We love to create our own adversities. We love to put obstacles in our path.
So, what next?
