For years, i've told people "you can't eat what you don't have." This applies to both junk food we want to eliminate from our diets (don't buy it at the store - DUH) and the good foods we want to make staples of our plan (can't cook & eat them if you don't acquire them first). Turns out, this is something behavioral neuroscientists call choice architecture, or a system of creating better default environments for ourselves. **Workbook Exercise: Where and how can you use Choice Architecture to create better defaults in your daily life?
