I'm a bit of a tech geek myself.
Predisposition is not predestination.
I love sports, as all Bostonians seem to. I love books and movies, as all writers seem to.
You know, being confident isn't the same as being right.
You can write a great book and be ignored. Literary history is full of classics that were under-appreciated in their own time.
Probably careful plotting reflects my personality. I am meticulous by nature. I can't imagine speed-writing anything that happens to pop into my head.
