I'm currently in a "Why do I bother?" phase with my writing.
A good question.
It’s a hobby.
It’s art and we need to suffer for art’s sake.
Write, or watch TV.
Write for fun (not easy to maintain).
Write for the challenge (all too easy to maintain).
That and more.
For me, I’ve always written. I’ve had on and off phases (sometimes lasting years), but in the end I always return to writing.
If your writing for success and publication you’ll always be under more pressure than writing for the joy of writing. I do of course want to be published, but as it takes a year to do a book (my average anyway) there won’t be many opportunities to get published. But as writing helps me relax (mostly, there are days when it doesn’t), I write.
So I write (active (a nod toward the thread I’ve hijacked)).
