“They said they’d do it later. It’s Sunday at 10pm, and later never came.”
To you, “do your homework” is one instruction. To your teen, “write the essay” is really four decisions: pick a topic, find the notes, decide how long it should be, choose where to start. Nobody wrote those decisions down, so the assignment has no visible way in. “Later” sounds like defiance. Most of the time it’s what a person says when they can’t see the first step.
A Friction Cutter removes one barrier between your teen and the first action. Not the whole assignment. Not a new system. Just the thing standing between them and starting.
