Trying to be More Active... How I'm Not Suceeding

The funny thing about making an effort to be more active is that when you miss just one opportunity to stay active, you lose almost all the motivation you've been building up. At least, that's how it works with me. I probably shouldn't admit this, but every now and then when I'm dedicated to some physical activity, I'll come up with some excuse to ditch it at the last minute so I can instead stay at home and watch a movie, TV show, or just sit around doing nothing. Perhaps recognizing this failing in myself is what will help motivate me to stop doing it.

There are two things in particular that I don't want to slack off on - yoga and soccer. I'm not going to lie, I'm not particularly flexible and I'm pretty crap at soccer. I'm the worst player on our team. Last game, I scored a goal for the first time. The problem is, it was against us by an accident of my foot being in just the wrong place at the wrong time. But it still happened.

Despite the fact that I really enjoy both soccer and yoga and feel the physical benefits of them afterwards, why is it that I have trouble motivating myself to go there in the first place when it's time to start? Even though I know how much better I feel physically, mentally, and even emotionally after engaging in these activities, I don't always go. And I don't always have a good reason for skipping the activity.
