Goodreads asked Larry Beinhart:

What’s your advice for aspiring writers?

Larry Beinhart Forgive me being slow to answer these. I didn't even know this section was here.
What do you like? What's there a market for?

The former because why would you write things you don't like? You might as well have a job.
If there's no market, you will have to have a job (or an inheritance or rob convenience stores or sell your body).
I suppose that writing to sell could be "selling out," (though it's harder to find buyers than people imagine), but it is also a form of discipline. It means writing to communicate.
My personal opinion is that a lot of what is taught about writing is quite misleading. If you want to know why I say that and what I mean in detail take a look at my book How To Write A Mystery. It's applicable to any form of fiction.
