I know exactly how you feel. I also felt upset trying to fulfill requirements of someone else when I felt that I could be steering the ship instead. I found solace in two different paths: (1) consulting: I find it more enjoyable to help people with their projects on a temporary basis and enjoy the interaction with clients (compared to the long death marches to help someone else make it big) and (2) my own startup which is so challenging that it always keeps me excited. But also, I look back fondly and with some regret at my first job out of college at a mega software corp that paid me well, treated me fairly, and demanded not too much in return. If I could do it all over again, I think I should have stayed there for many more years than I did.
