I've been spending the last few days reworking the statistical portion of our product. After a year and a half of using it and watching other people use it, it's very exciting to be on the other side for a change. And as someone who's fascinated by the visual display of quantitative information, it's been a lot of fun to take apart and put back together in what I hope is a cleaner, better, more elegant way.
Honestly, it was hard to muster this kind of enthusiasm for my old job; even though I really enjoyed the work, it boiled down to doing the same sorts of things over and over for each client, and it eventually got to feel like I was treading water. With my new job, I finally feel like I'm getting somewhere because I'm working on our own product, working to improve it in ways I really care about. On a given day, I might or might not accomplish a lot, but every little thing I manage to fix improves the product in a tiny way. We'll be pushing to production very soon, and it's cool to have that kind of nearly instant gratification.
Plus, now I get to say things like "pushing to production". Hott.
