Friction on the Impulse, Simplicity Over Optimization

This lesson handles the impulsive ones, the unplanned buy, the 1am cart, the "treat" that wasn't in any plan, and it uses the exact tool you built in Module 9: friction plus an easy exit. Recall the finding: a brief obstacle in front of an impulsive app-open led people to abandon about 36% of the apps they'd just reached for, and the surprising part was that the easy way out did more of the work than the wait did. The same move maps onto spending. The wall: delete your saved payment info from the shopping sites and your browser, so every impulse buy requires digging out the card, a small obstacle that gives the deliberate part of your brain a moment to get a vote. Separate your accounts (a discretionary account distinct from bills and savings) so impulse spending hits a visibly limited pool, not your whole balance. Put a waiting rule on non-essential purchases, a 24-to-72-hour pause before buying anything over some threshold you set, because the impulse that feels urgent tonight is usually gone by Thursday. And the door, which matters more than the wall: make the not-buying path the easy one, close the tab, the item's still there in three days if you still want it, and you almost never will. But here's the rule that protects this entire module, and it's the most ADHD-specific thing in it: simplicity over optimization. There is a perfectionism trap that ruins more ADHD money systems than impulse spending ever does, the elaborate budgeting spreadsheet, the four-app tracking setup, the zero-based system with twelve categories. It feels productive to build. And it is guaranteed to be abandoned by week three, because it's high-friction, high-maintenance, and runs on the exact sustained-attention fuel you don't have. The foundation says it cleanly: "one automated bill-pay beats a sophisticated spreadsheet abandoned in week three." That's the whole philosophy. A crude system that survives beats an elegant one that doesn't. So when you feel the pull to build the perfect financial dashboard, recognize it as the week-three cliff (Module 8) dressed up as diligence, and do the opposite: make it simpler. Three automations and one friction barrier that you'll never have to think about will out-earn the most beautiful spreadsheet you'll stop opening in a month. Boring and running is the goal. Impressive and abandoned is the trap.
