First of, all happy Remembrance Sunday! These are very 'lest we forget' times.
More and more, I'm relying on github's projects feature to self-organize and get more coding done for personal projects. I use it to plan out a mini-roadmap using the project notes feature as follows:
The process has minimal overhead for one person, pairs or small teams. It allows you to focus on one thing at a time. It allows small features to roll off the production line at regular, predictable intervals - and a sense of accomplishment accompanies each completed ticket.
It also allows you to go back in time and see exactly what you worked on and what was delivered, and when.
Give it a shot if you haven't tried it yet! :)
