Because when you are tired nothing good happens.
And your body and mind both suffer because you are not giving them what they crave – a break, rest and sleep.
Don’t torture yourself.
Stop when you feel tired.
This is such a simple thing that we often don’t pay attention to how we feel after a long day’s work.
Stop when you see the brain getting tired, because that’s the first signal you get. Don’t wait for the body to give signals because that comes later.
If you can stop work at will, smile, because you have a superpower.
