When I first started writing I got very excited. Then again, I was eight, I was excited about everything. That didn't last long though (as eight year olds are prone to get excited about something else entirely). Oh, don't get me wrong, I knew I had "the bug," just that I wore out for a bit.
My next big surge was when I was twelve, and then again at fifteen. Up until I was in my 20s, it came and went with the tides. Afterall, I didn't have to worry about making money with it, so doing it as a hobby was just fine. Then I had a few articles printed in a very local newspaper, which, while it wouldn't make ends meet (heck, it barely paid for the ink) made me feel like I was progressing.
Then I realized, I really don't want to do non-fiction...novels were where my heart was at (besides, getting paid was touch and go...and once the newspaper went belly up, I figured moving on was best). On and off some more until I was about 28 and I destroyed everything I had created up to that point and stopped for a year. Didn't even pick up a pen except to sign a check.
About a year after that, it became touch and go again until I was in my mid-30's at which point I said "Dang it, I'm going to write every danged day or die trying." A couple more novels tossed (for different reasons) and here I am.
