Why think in opportunity cost?

Money gets a budget. Time usually doesn't, even though it's the one resource you can't earn back. A 30-minute habit feels tiny on any single day, but repeated for years it can add up to months of your life.

We want to help you identify where your time is going and how to take it back.
