I'd love to hear more about how people are motivating themselves! That seems like the hardest part of all, to me.
As it is, I've been having a hard time with motivation for exercise. Grad school is rockin me hard, and my boyfriend's schedule is pretty tight but we're trying to work out together. Our only time to really work out is in the mornings... but I HATE mornings. I can't figure out how to get myself to stop hitting snooze! I look in the mirror and see the things I want to change, and I feel a little guilty that I'm not doing more, but some days I just can't push past it.
I saw on another website something they called "The 5-minute rule," where you can whine as much as you like but you force yourself to start exercising and do it for at least 5 minutes. After 5 minutes, if you still don't feel you're up to it today, then you can stop knowing that you tried and still be proud that you did that. I think that'd be a great motivator for me; instead of feeling down on myself for not even trying, at least I'll feel like I tried, and then that bit of pride I gain will push me to try again the next day, until I can do the whole 30-45 minutes or what have you.
For the diet changes I've made, I've actually been doing really well with staying motivated to stick to that. I think it's thanks to the "free day" once a week, lol. Since I started by branching off from the "Body for Life" diet plan, I went with the 6 days of dedicated healthy eating, 1 day free idea, and it's really working for me. The free day is a great reward for sticking with it all week.
