This really hits home with some thoughts I've had lately. But I'm caught in a trap. Do I go after my dreams (numerical computing), do something useful (continue working with the non-profit I help out with), or continue being a sellout by working and learning things relevant to my employer? Splitting my time does not seem efficient, but consuming less and creating more would mean I'm at least working towards several goals slowly than not at all.
