Anybody else with any wisdom or suggestions or whatever?
Working as a professional writer is always a "gamble" in the sense that you mean. Whether you work on features or in television, there's no such thing as a guaranteed paycheck for a "writer."
Even if you happen to make it as a staff writer -- which is a tremendously competitive enterprise, there's no guarantee that the show you're working on will be on next year.
But what if it's an incredibly successful show? Surely that's some kind of guarantee.
Really? Ask the writers who were working on "Three and a Half Men." One of if not *the* highest rate shows on television. Where are they going to be working next year?
And even if the show goes on, it's quite common for writing staffs and members of writing staffs to get "turned over" -- here one season, gone the next.
There are, in both television and motion pictures, a small group of writers who have some version of job security. In television, they are the writers who have moved up and become successful writer-producer show creators and who get into the business of creating and producing often many different shows for network or for cable television.
Very few people ever achieve that level of success.
In motion pictures there are a small group of very successful screenwriters, some of whom become "hyphenates" -- writer-producers or writer-directors, some of whom simply remain writers, but who achieve a sufficient number of very successful movies and establish on-going relationships with one or more successful director that they will pretty much always be able to find work for the majority of their working lives -- and will be extremely well paid for it.
Likewise, this constitutes a very small minority of screenwriters.
The rest of poor saps just have to work for a living. No guaranteed job security. You get an assignment or you sell a spec -- great. If it's a decent sale, that means your bills are likely paid for this year and maybe next. If it gets made (which happens maybe one time in ten) then you'll make even more money -- checks will keep coming. Otherwise, you hope your agent will keep looking for assignments or you'll have to start working on another spec.
If you work in TV, if you're working on a show -- great. You've got work. For now. And so long as the show runner likes you and the network likes him, and the show stays on the air, you'll keep getting credits and taking home paychecks.
Any of the above stops happening -- you're out of work. Of course, with TV, you'll keep getting residual checks, so that should keep you going while your agent sends out your sample scripts and you go around town trying to get some more work and go back to working on that feature spec that you've been polishing for the last few years.
Maybe that'll sell and you'll be able to break out of TV after all. Or maybe you and your friend, who've been working on a pitch for a new series will have a chance to pitch it because you've earned enough credits (after years in the trenches) to get somebody to actually listen to you, and you might have a chance to step up.
Maybe. But nothing's guaranteed. You get a job, you get an assignment, you get a staff position, you sell a spec, you get something optioned -- congratulations. Enjoy it while it lasts.
When it's over, it's over and you have to start all over again. New job, new assignment, new spec, new staff position. Maybe it'll come next week, next month, next year -- or who knows when?
If you wanted job security you should have done what your mother said and become an accountant.
If you want to be a writer -- this is all part of the job description.
