Weniger aber besser. The English translation is: Less but better. - Greg McKeown

Effort and results do not share a linear relationship.

Essentialism is a disciplined, systematic approach for determining where our highest point of contribution lies, then making execution of those things almost effortless.

You don’t have to be overwhelmed by essential projects. Often, when you name the first obvious step, you avoid spending too much mental energy thinking about the fifth, seventh, or twenty-third steps. It doesn’t matter if your project involves ten steps or a thousand. When you adopt this strategy, all you have to focus on is the very first step.
