I know I've mentioned before about how I tend to hold more things close to the vest lately. So I'm not going to say what I've been working on lately in my spare time, but I will say that I've reached a pretty high level of motivation. Tonight is the first evening in awhile that I've just backed off and left the computer off.
I've learned that I have to take advantage of these sprints (not to be confused with "Agile" sprints) as best I can, because they don't last. I mean, there's a reason that the current version of CoasterBuzz, not counting the many new features added since, is about 3.5 years old. There is actually quite a bit of inspired work going on lately, with sketches, prototypes, experiments and general geeky hacks.
Part of it is also the desire to stay sharp. My current gig doesn't have much opportunity for writing code, so I need to spend time outside of work doing the things that I think make me well-rounded and someone that people will listen to. Plus, there is so much in the way of new stuff to explore lately. Things I couldn't conceive four years ago are so much easier now. I feel less constrained.
