You ordered a pair of shoes online. They arrived, and they don't fit. You look at the return policy: "Free returns within 30 days!" You repack the shoes in the original box and leave the box by the front door so you won't forget them.
Day 5 passes. The box is still there. Day 14. You start feeling a twinge of guilt every time you walk past it. Day 28 arrives. You know the window is closing, but the thought of finding a printer for the shipping label makes you physically exhausted. Day 32. The window is closed. You place the box in the back of your closet, out of sight, accepting a $150 financial penalty because your brain refused to drive to the local UPS store.
For a neurotypical person, this behavior is utterly baffling. "Just print the label and drop it off!" they say. But for an ADHD operational system, a return is an administrative nightmare. The ADHD brain thrives on high-stimulation, high-reward tasks. Buying the shoes was a dopamine rush (novelty, anticipation). Returning the shoes is an administrative chore (low-stimulation) that results in a net-zero gain (you are just getting back to where you started).
The prefrontal cortex lacks the transmission fluid to initiate a 7-step sequence that has no chemical reward. Furthermore, if even a single step contains friction (e.g., you don't own packing tape), the entire process violently halts. To combat this, you must stop relying on willpower to get to the post office. You must either alter how you shop, or completely outsource the return process.
