When the laptop freezes, a restart fixes it half the time. Sometimes a night of sleep is your restart.

Some problems are not solved, they are cleared. When a system has too much running, nothing is broken exactly, and the accumulated state alone is enough to stop it working properly. Minds behave the same way after a long stretch without a break, which is why the sensible answer to certain evenings is sleep rather than effort. Rest is a legitimate diagnostic step.

When you are stuck at eleven at night, stop and come back in the morning. Write down where you left off so restarting is cheap. If it looks different tomorrow, the problem was your state rather than the task.
