There comes a time with almost everything that you start losing concentration, making silly mistakes, and generally going crazy.
It’s almost never a mistake to walk away – for ten minutes, for an hour, for a weekend – and do something else, and ideally to find help.
We usually also recognise crazytime too late – we hang on, we flounder, and waste a lot of time building up the courage or will or perspective to put down our tools.
Tell yourself: “I am someone who is good at stopping at the right time.”
Then do it – remembering the lessons of double time.
