Daniel Coyle, the author of The Talent Code, keeps a blog on his site. A while back, he posted about "practice maps" in the entry entitled "Steal This Idea, Please" The idea is to have a score card that you make a check on every time you train or practice. One session = one step closer to your goal.
"Practice maps" are common in Japan. I bought the practice maps below in Japan. They were meant for kids to affix a Dragonball "well done" sticker each time they did their chores, but it can work equally well for training.
I've tried this just to get sessions in and it works!
Use it for the things that are tough to do, or for actions you want to make habitual. For example, windmills and bird-dog pose thingies are two exercises that I should do on a regular basis... but don't. Using a card like this and throwing on a sticker each time I get it done is actually motivating!
