Adding rewards to goals.
Any goal can have a reward assigned to it.
Rewards can be anything you designated, from a nice meal out at an expensive restaurant, to a day of binge-watching Netflix, to a vacation to the S. Pacific.
While goal achievement in itself is a reward, you should reward milestones along the way which helps fire your feedback loop.
Partial rewards is what keeps motivation fired, and momentum moving
When you mark a goal complete, you can elect to have your Reward moved to your Backlog.
