You are right on both accounts, @bitdollar! It is good to reward yourself when you have accomplished a goal. It is also good not to reward yourself too generously or too often.

I have done some really challenging indoor rowing competitions for nothing more that the sense of completion, and a pin.

I've kept on going through the miles of a marathon with the thought of the food reward at the finish line.

In both situations, finishing the goal was important to me, but the reward at the end is what kept me going through the difficult spots.

I've upvoted and resteemed this article as one of my daily post promotions for the @mitneb Curation Trail Project. It will be featured in the @mitneb Curation Trail Project Daily Report for 22 FEB 2018.

Cheers!
