My old job consisted mostly of maintaining and adding minor tweaks to mature codebases. Working on my own projects has given me a chance to do clean-slate architecture again. The things I've been working on (machine learning, DSP and OpenGL) are a lot more interesting and challenging than the corporate CRUD apps I was working on too. I have to be ruthlessly efficient with my time now that I can't count on a salary, so I've gotten a lot better at focusing on getting features done fast.

Travel itself is somewhat incidental to all this, but it's given me a tremendous incentive to make this experiment work because I want to keep traveling. Exposure to new cultures has also given me some ideas for new projects and given me a lot of aesthetic inspiration.
