I joined a gym today! I get a lot of exercise what with my gardening round, weekend cycle ride and now Parkrun, but I don't get to do yoga or meet that many people during any of those. So a gym seems like the cheapest way to do yoga a few times a week and meet some people.
I'm reading this book on reflection in Buddhism and the author talks about people not liking doing nothing or just not having the time to sit and do nothing. Literally nothing. I don't have that problem: I've been doing zazen regularly for over 10 years and inevitably my way of thinking has changed and I have developed a habit of doing nothing! Some of my happiest times, moods and moments are when I'm sitting zazen and so I associate doing nothing with being happy. The bits inbetween exciting events are great too.
When you look back, you also want to have something to look back upon. Stuff is fun to do, places are waiting to be seen. There are adventures to be had. Making friends and doing things you are scared of is liberating.
The fact that I don't have trouble making time to do absolutely nothing is a good sign that I have too much spare time that could do with filling up with something other than nothing!
So I joined a gym.
