Пара цитат из блога mark kennedy (один из сценаристов Disney)

All artistic projects are foolish, of course; in doing anything original and sharing it with the world you're making yourself vulnerable and opening yourself up for ridicule and rejection. In doing your own personal thing, you're sacrificing your precious free time and running a huge risk that all your hard work will lead to nothing. It's a daunting task and that's why almost all projects that are undertaken are abandoned and forgotten and never see the light of day.
There are always many more good reasons not to do something than to do it. I don't have any good reasons to do what I'm doing; I really don't have the time to do it, and I'm not planning on making any money on it, and yet...I've really enjoyed doing it so far and somehow it feels like something I just have to do.

и про сюжет

I found while I was working on the story that it had three elements that I think make for a good story:

A world you'd live in, if you could.

Characters you'd hang around with, if you could...

...facing problems you'd never want to face in a million years.

...
We all know how hard it is to work on your own projects and come up with your own stories, so the other good thing about these rules is that, as long as you're going to go through the torture of working on your own thing, at least you'll be spending your time with characters you like and in a world you enjoy being in.

Насчёт третьего правила - это, скорее, относится к приключенческому жанру. В остальном всё хорошо ложится на любое хобби.
