I am committed to doing something new every day to improve myself.

New is a low bar on purpose. A different spice in a recipe you've made a hundred times. Saying hello in the shopkeeper's first language, badly.

Committing to it daily works because it kills the deliberation. There's no debate about whether today is a good day for it. The only live question is what.

The compounding isn't in the individual things, most of which won't stick. It's in becoming someone for whom unfamiliar has stopped being a reason to stop.
