If I’m stuck in some part of the high-level design, starting to work on the implementation is often the best way to get unstuck.

One such idea, which is really simple, but tends to lead to better and simpler code, is the idea of defaulting to zero. I.e. to always use 0 as the default or nil value. For example…
