Screenplays are not writing. They're a fake form of writing. It's a lot of dialogue and very little atmosphere. Very little description. Very little character work. It's very dangerous. You'll never learn to write.

The home environment can undo a lot you try to do at school.

I've written about 2,000 short stories; I've only published 300 and I feel I'm still learning. Any man who keeps working is not a failure. He may not be a great writer, but if he applies the old fashioned virtues of hard, constant labor, he'll eventually make some kind of career for himself as a writer. Ray Bradbury, 1967 interview (Doing the Math - that means for every story he sold, he wrote six "un-publishable" ones. Keep typing!)

Cram them full of non-combustible data, chock them so damned full of 'facts' they feel stuffed, but absolutely 'brilliant' with information. Then they’ll feel they’re thinking, they’ll get a sense of motion without moving. And they’ll be happy, because facts of that sort don’t change. Don’t give them any slippery stuff like philosophy or sociology to tie things up with. That way lies melancholy.

If you love people you criticize them, and if you don't love them you don't criticize them, you let them go to hell, don't you? To help any kind of friendship, your marriage, your children, you criticize because you love.

My characters talk to one another, and when it reaches a certain pitch of excitement I jump out of bed and run and trap them before they are gone.

If you had your way you’d pass a law to abolish all the little jobs, the little things. But then you’d leave yourselves nothing to do between the big jobs and you’d have a devil of a time thinking up things to do so you wouldn’t go crazy. Instead of that, why not let nature show you a few things? Cutting grass and pulling weeds can be a way of life, son.
