A journal also makes it much faster to jump back into a productive state after that inevitable interruption. (That interruption could be a meeting, or an emergency that forces you to drop everything and work on a higher-priority issue for several days.) You can also refer back to your journal to remind yourself how you fixed that similar problem months ago. Of course, a journal doesn't have to be limited to debugging. It's useful for development too.
