"I’ve adapted and refined your system over the years to tailor it to my specific needs, but the core lesson/strategy is still there – do it, delegate it, delete it, defer (and schedule) it. It’s a litmus test that I can apply to everything that crosses my desk and lets me balance my work and personal life much more effectively than I did before. I’m more predictable and believable than many of my colleagues because I make the time to do what I say I will do and am up-front when I can’t do something (because of higher priority things) for someone else that they would like me to do. It’s a key differentiator in my environment and 'integrity' has become a core value of mine as a result. Thanks for the incredible (and amazingly simple) concepts that have literally changed my life."
