Don’t rewrite your whole schedule after one bad day. Fix the one thing that broke.

A single failure invites an overcorrection that wrecks the parts that were working. When a day collapses, the instinct is to redesign everything, which conveniently delays the dull job of repairing the one piece that actually broke. Most plans do not fail as a whole. They fail at a specific joint, usually the same one twice.

After the next bad day, find the exact point where it went wrong: the late night, the missing bag, the hour that disappeared. Change only that and leave the rest of the week alone. If the same joint breaks again, you have learned something worth redesigning for.
