The easy option.
I bought a NutriBullet this week. I already had a Philips mixer that works decently well. I was worried I'd made an impulse purchase that wouldn't be of much use.
The whole day today, whenever I felt hungry, I put stuff in the jar and made a smoothie. It was just the easier option. Even easier than ordering a meal from a delivery app.
No willpower needed. No rationalisation needed.
The only thing needed was for the easier option to become the healthier one.
