Um, seventeen? I'm only kidding, lol, well sort of. I've started close to 30 projects over the past year and a half, and I'd say I have 8 finished. I usually get distracted or too excited about a new project before I finish the current one, and I just can't wait to start it. They're WIPs because they're unfinished, but I can't tell you when I plan on finishing some of those.
I'd say I'm actively working on three projects at the moment.
