My brain sometimes break and wants to do something to completion.
Once. every single item at a fast food restaurant had to be had for lunch. It took a few weeks. Once it was every rendition of the Bach Chaconne I could find. Twenty-four of them.
The last few items on the fast food menu were dessert wraps. I had five desserts for lunch for a week.
That is tangible upside to an action to be endured.
