Lots of people want to have written; they don't want to write. In other words, they want to see their name on the front cover of a book and their grinning picture on the back. But this is what comes at the end of a job, not at the beginning.
It is not necessary to have enemies if you go out of your way to make friends hate you.
I always treated writing as a profession, never as a hobby. If you don't believe in yourself, no one else will.
