Enough
Enough — the computed threshold past which further accumulation stops buying life outcomes: annual burn (5.1’s number), a conservative real return, a withdrawal-rate sanity check, a safety margin. Computing it converts the final phase gate from a feeling you wait for (and never feel) into an engineering target like every other number in the course. Its absence has a known failure mode: the optimizer who runs the machine for twenty extra years on autopilot because no number ever said done.
