Conventional wisdom is not to put all of your eggs in one basket. 80/20 wisdom is to choose a basket carefully, load all your eggs into it, and then watch it like a hawk.

The 80/20 Principle, like the truth, can make you free. You can work less. At the same time, you can earn more and enjoy more. The only price is that you need to do some serious 80/20 thinking.

Our current use of time is not rational. There is therefore no point in seeking marginal improvements in how we spend our time. We need to go back to the drawing board and overturn all our assumptions about time.
