Set all your clocks 0 minutes ahead so you're never surprised by the real time

People set their clocks five minutes ahead to trick themselves into being early. The flaw: you know you did it, so you subtract the five minutes, and now you’re doing arithmetic and running late.

Setting every clock exactly 0 minutes ahead eliminates the mental overhead entirely. Every clock in your home will show the actual time, with zero conversion required. You will be exactly as late as before, but confidently.
