Next year's theme for me is "economy of motion". It's a Wing Chun concept, and somehow work, training, and everyday life all include this concept of valuing efficiency and simplicity.
With swimming, it's a focus on balance and form. With cycling and running, it's high cadence — 90 rpms. With work, it's looking to create the most efficient products for interacting with the Web. With everyday life, it's balancing all the different things I need to do in one day, week, month. I already see several areas that will be changing, including diet, communication tools (decrease IM usage), and better use of calendars (work, workout). And with Firefox and Thunderbird, there's still plenty of room for improvement.
