Setting up a system of rewards for accomplishing diet and exercise goals, in which specific goals lead to specific categories of rewards could help your motivation.
When it comes to motivating others and ourselves, it turns out offering rewards in defined categories, even when they are largely meaningless, can heighten motivation.
... even if the rewards are the similar -- and the categories arbitrary -- the very act of segmenting rewards motivates people to perform better and longer, even on menial tasks.
"It was really the desire to eliminate the fear of missing out that led to people work hard when there were two different categories," said Wiltermuth. "If they couldn't eliminate the fear of missing out, which would be the case when they had more categories of items, they didn't work very hard. They were at levels comparable to the single category."
"This also could apply to individual goals in the context of, dieting, for example. Wiltermuth, said, "If I drop five pounds, I might get this type of reward. If I drop another five pounds, I'm going to get another type of reward."
In sum motivation boils down to this says Wiltermuth, "Instead of presenting one big reward, set up a few small rewards. Even if they're not all that different, making people think they are different can get people to devote increased effort in pursuit of those goals." "Creating excitement just simply by categorizing rewards could be a key way to get people to try harder, and devote more time to tasks." [emphasis mine]
