SEE THE PRACTICE
Turn a thought this research explains into one clear move.
THE THOUGHT
“I just need to try harder”
YOUR RECORDED RESPONSE
“I’m not missing effort; I’m missing a start signal that actually works.”
ONE PRIVATE MOVE
Within the next 10 minutes, place the task object in a more obvious spot and add one private cue beside it, like a sticky note with the next tiny step or a phone alarm labeled with that step.
