“The easier I make it, the less they do.”
This is the counterintuitive one. Your teen dodges the simple worksheet, then pours three hours into a complicated project. You simplify the worksheet to help. They do even less. An ADHD brain runs on stimulation, and easy is under-stimulating: no challenge, no dopamine, no start. Easier was the wrong direction the whole time.
When avoidance shows up, raise the bar instead of lowering it, and keep your voice playful, because playful-hard pulls the brain in and anxious-hard shuts it down. You are adding interest, not pressure.
