What you resist, persists. So goes one of the oft repeated sayings of the self-help movement.
I have resisted writing for quite some time now. I wrote a few pieces for a student magazine but didn't give my name or get involved with the magazine. I went to a creative writing class, but stopped when I felt I couldn't generate good enough material.
And now, when I'm about to leave my job, I still say "I don't know" when asked what I will do next.
But finally I have admitted to myself that not only do I want to write, I will write - regularly and until it's any good. Hold me to it.
