First I was very suspicious of another click-bait article.
But what followed was great ideas and a good article.
Why don't you use a title like: "What could you do with 20% more time." "Be a better designer, while doing less"
Or something like that.
At least since a year, all this clickbait article titles are just annoying, and actually don't movtivate me to even start reading it.
It worked well enough for me to stop reading the article and actually start doing what I needed to do (after commenting here, of course).
In economics, this concept is called scarcity, or not having enough of a resource (usually time or money). The inverse is called slack. Here, margin = slack.
In their book Scarcity: Why Having So little Means So Much, the authors present evidence that scarcity literally changes how the mind works, usually for the worse in a lot of situations. If you're interested in this topic, I highly recommend this book.
This is a really, really great concept. Thanks for posting! It is one of those things that should be obvious--we all strap our selves too thin. However, we all fall into this same trap over and over again. If you're serious about making this change in your life, take a listen to this message about building healthy margins into your life. It is a message that has truly helped me in more ways than I even know.
My complete, fair and honest warning: this message also deals in topics of God and Religion... just giving a fair heads up. Regardless of what you believe, though, I believe this is certainly a more-than-helpful message for anyone.
Anyways, here it is: http://www.hopeinjesus.org/hope-messages/item/226-crazy-busy-part-1-margin
