"Do 100 of something. Then figure out what to do next."
It stuck in my head. It feels like an ideal midpoint between trying new things and committing to a long term habit. I instantly felt it had to be my New Year's #resolution. So many tasks need a certain investment of time & effort to pay off -- but not a lifetime or even a year.
First on my list: fold 100 origami pieces. I loved origami as a child but haven't returned to it since. After that I'll pick a new "something" for the next 100!
