Quality Time means you need less time to do it right.
To give yourself quality time, you need to manage your mind, not your calendar.
Do I really need to be involved? Is it the right time for this? Is it the right time for me to do this? Can I postpone or delegate?
Don't get sucked in by curiosity, sunken costs, the need to control something, or the idea that you can push through. These are false promises that trick you into long, inefficient hours.
Other opportunities will come.
