Wow, so that was hard, I definitely didn’t stick to it, especially toward the end.
I think certainly doing some programming each day, is quite a hard goal. Compared to something like say, making your bed, programming, no matter how small it is, involves engaging the brain, and that can be difficult.
But that said, the effort to work on it each day, did get work done. So I think definitely worth doing again.
But at the same time, I think more gets done in longer sessions. I think the real key for programming, is to constantly be adding the small items (eg. ask that question on Stack Overflow) to your backlog, and those smaller items can be done in the evenings.
