It always takes longer than you expect, even when you take Hofstadter's Law into account. Estimates are optimistic by nature, so build in real slack.

The home renovation
Quoted at six weeks, it runs three months — and the 'buffer' you added gets eaten too.
The software ship date
The feature is '90% done' for weeks; the last 10% hides most of the work.
Packing for a trip
'Five minutes' to finish packing reliably becomes thirty.
The group project
Everyone plans for the best case, and the deadline still slips past the padded estimate.
Writing the report
You account for delays, then new delays you didn't imagine arrive anyway.

For complex or novel work, don't promise precise dates — build in slack and treat the plan as a hypothesis reality will revise.
Ship in small increments so each unforeseen surprise is small and recoverable, not a schedule-wrecking shock.
When you think 'this time I've accounted for everything,' smile — that's the exact thought the law predicts is wrong.

That's just how memory works. Lock hofstadter's law in with a 5-minute active-recall session — spaced repetition, no signup.
