Fixed-scheduled productivity: “Fix your ideal schedule, then work backwards to make everything fit — ruthlessly culling obligations, turning people down, becoming hard to reach, and shedding marginally useful tasks along the way.”
A big part of this: saying no. The author gives Jim Collins as an example:
Even though Collins demands over $60,000 per speech, for example, he gives fewer than 18 per year, and a third of these are donated for free to non-profit groups. He doesn’t do book tours. His web site is mediocre. He keeps his living expenses in check so that he’s not dependent on drumming up income (he and his wife have lived in the same California bungalow for the past 14 years), and he keeps only a small staff, preferring to bring on volunteers as needed.
Also shows the freedom you get from having low overhead. The less you owe, the less you have to do things you don’t want to do.
