This is a quick little way to do the classic activity of filling the jar with rocks of different sizes to see how you can get them to fit!
The Largest Rocks represent Big Commitments, like going to class. (You need to be sure and fit all of these in the jar!)
The Medium Rocks represent Tasks, like doing the laundry. (These are important, but not critical.)
The Small Rocks represent Stuff, updating Facebook.
The Tiny Rocks represent Fun, like playing a game on your phone.
