I remember Markus calling his interests "serial hobbies" once - he gets really, really into what he's doing, and learns everything about it and gets really good at it, and then, after a few months, he loses interest. I'm not a serial hobbyist, I've got seasonal diversions. Really, I'm quite consistent in what I like to spend my free time on - every fall, as the days turn to gloomy, I fever toward the snow and spending time on skis and snowshoes. Near the end of winter, I think really longingly of being out in the kayak, I start to ride my bike, and I play musical chairs with the perennials in my garden. 
When it gets hot, I forget about the bike and the garden except for occasionally running my push-push mower over the tiny patch of grass because I wish that every weekend were a three day weekend because I'm still so in love with the kayak camping thing. In the fall, as it starts to cool off, I am back in the garden and contemplate a hiking trip right around Thanksgiving (it doesn't always happen). And then we're at repeat.
See what isn't in that list of things I look forward to with every season? That's right, the gym. I don't *like* the gym. I don't like going there and running on a treadmill or dripping sweat on a stationary bike or balancing on some stupid ball while lifting a dumbbell. I don't hate it, and the gym I belong to is posh and lovely and all. But I go to the gym so all the things I like are more fun, not because the gym going itself is fun.
And now, it is spring, and I am convinced we should be moving into the part of the year where I look for the crocuses to pop up in the garden, ride my bike, and start thinking of early season paddling trips. My garden, however, is under almost a meter of snow, and I suspect it will be May before I go paddling. But my bike! I can ride my bike! The roads are dry, and thanks to all those hours in group cycling classes, I don't have that sore butt from the first ride of the season thing going on. Really, it is quite cool to be able to hop on the bike after months away from it and have my muscles be so good about it.
This of course only means that I have a different limiting factor now: my feet! Yesterday, it was - as seems to be the case around here lately - a little below freezing. It was also Good Friday, which meant that I chose to view it as a bonus day (there are all these *things* that need to be done on weekends, things like grocery shopping and floor washing and errand running, but there is still Saturday for that...) and I had time for a longer ride. I put on my layers: polypro long undershirt, fleece sweater, wind shell on top, thick running tights on bottom, winter weight wool socks, sealskinz and bike shoes, wool toque and helmet, and windblocking gloves. I started riding. Everything was fine until about 15km in, when my feet started feeling cold. Since my legs and lungs and enthusiasm were fine, I kept going. 
My feet kept getting colder. At the 28km mark, I stopped to sit on a piece of fence rail and eat my lunch, and even though my feet were sitting in the snow they felt warmer. I concluded it was due to the wind, and rationalized that since I'd been going *into* the wind, if I turned around now the wind would be behind me and there would be no problem.
At around 45km, now flying along with tailwind, I thought my feet didn't feel cold anymore. At 60km, I was home, and I took off the stiff bike shoes and realized that from the ball of my foot to my toes was completely numb. I prodded the toes with my fingernail, and I felt that, so whatever, all is good. Except for the part where the feet started aching, so I chose to ignore all the useful stuff I learned in that Wilderness First Aid course and decided external heat was the way to go to make this better fast. I stuck my feet in a bucket of warm water. And wow, that's not a mistake I'm going to be making again. My angry red toes sent a burning message to my brain for a couple of hours, and if I think of going for another bike ride today, the burning starts again. I'm not kidding.
I need to figure out a better way. I wonder if I can find toe cages big enough to take sheepskin boots? Maybe the
