I feel like it has gone very fast for me, but I feel like it wasn't instantaneous, at all. I was getting a lot of rejections. I just got very lucky and it happened quickly for me. I don't feel like I'm a prodigy or something. ↗
The usual way - through a long series of rejections, revising my manuscripts, and kept trying again and again. Finally I was fortunate enough to find a good agent. ↗
I have friends that are much better actors than I am that had to quit the business because they couldn't survive the auditions or the rejections, or people just didn't realize how good they were. ↗
