By concept, Micro Rewards is simple. We get rewards all the time. A promotion, a salary hike or even a medal at the end of a certain period of time serves as a reward. We feel happy and motivated when we get it. Micro Rewards is nothing but small rewards which we give to ourselves for finishing smaller but important tasks on a daily basis. The rewards you give yourself should also have the bigger picture in mind, since these are the building block which will motivate to achieve your bigger goals. 

Mirco Reward is for tasks and Reward is for goals. Keep listening.
