Describe an example of how to utilize spare time?

The best way to utilize spare time is to be productive. Productivity helps your mind as well as helps you physically. Take a walk, Write in a notebook, call a friend, volunteer by talking to your local city hall, help with household chores.  I hope this helps.

Brownies are good but they're messier than cookies. sugar cookies are also fun and more versatile to decorate. especially cut out cookies.
