A writer is always working.
If you write for yourself, you'll reach all the people you want to write for.
Writing is learned by imitation. If anyone asked me how I learned to write, I'd say I learned by reading the men and women who were doing the kind of writing I wanted to do and trying to figure out how they did it.
You learn to write by writing.
Probably every subject is interesting if an avenue into it can be found that has humanity and that an ordinary person can follow.
