I used to be totally into cycling and training a couple of years ago, but things happen and your motivation falls. I ultimately ended up putting on quite a bit of weight and changing my interest. I went from bikes to cars. That kept my attention for a while. Until a few months ago, I got back on the bike for the first time in almost 2 years. Let's just say I have only one car now, and 6 bikes. Sometimes it just takes a break from it for a while. And it also helps to give yourself a goal to work toward, no matter how small.
