Last big resolutions I made were to give up cigarettes and alcohol, which I did four years ago and three years ago respectively. Once those two were conquered other resolutions didn't seem necessary. But...
This year I'm going to try to make more useful time to myself. Spending less time in work is top of the list. I'll never get it down to contracted hours, but I'm going to try to at least get under the WTD limits.
Less computer / internet time generally. Less mindless surfing. Get rid of the RSS feeds which keep distracting me. Waste far too much time following feeds.
Luddite Weekends. Anything with a chip (including the MP3 player but excluding the camera) goes in a cupboard on Friday evening and doesn't come out until Sunday evening.
Lose some weight. Weight has slowly been creeping up over the last three years; hit the magic 80kg mark early December which is the point where I really have to do something to get back down again. Less time sitting in front of the 'puter, work or home, would make more time for cycling and / or walking.
Since my illness a couple of years ago I've been building up distance again, and have been doing metric centuries this year. Next year I want to make it Imperial Centuries.
