This is spot on! While I don't have problems financially, but I feel very much unfulfilled with my day job working as an architect for a big enterprise software company.
Right now I do a lot of side jobs (architecture consulting) to get my creative juices flowing and keep me updated, and I always dreamed of starting my own boutique consulting company. I always say someday this someday that. It's hard to take that first step.
Unfortunately, I don't have the answer, and just last week I closed another side project (which made me happy because their problem was very interesting), on the other hand, office politics is really stressing me out.
