Luke warm
The perfect cup of coffee is gone in a flash. The heat has dissipated. The taste has dampened. The aroma has disappeared. Why keep drinking it?
If it was for the best experience then another cup could be brewed. If it was for the most energy then the cup would be finished before it cooled down.
Accepting the imperfections allows you to savor each sip for what it is and continue along with your day.
The thoughts to pen the perfect book, to make the perfect business pitch, to craft the perfect song - your mind can brew troubles before you get started. But if you all you did was wait for perfection, then you would still be stuck making a cup in the morning.
