After reading this post I decided its time to get started on my habit changing activities. I posted my answer in the comments on that site and I'll post it here as well
- The habit: not following my normal workout schedule
- The why: I need to get in shape to be more competitive for outdoor volleyball season, to prep for indoor volleyball season, to make myself more attractive to my girlfriend and to improve my self confidence.
- The difference: The deadline. Its not the most enjoyable, but I work well with deadlines and pressure. I'm going to find a volleyball tournament just over 30 days from now, sign up for it at one or two levels higher than I normally play. For me to have a prayer of doing respectably, I need to definitely be in better shape than I am now.
Update: Here's the tournament I think I'll put as my deadline:
