80/20 Thinking is my phrase for the application of the 80/20 Principle to daily life, for nonquantitative applications of the principle. As with 80/20 Analysis, we start with a hypothesis about a possible imbalance between inputs and outputs, but, instead of collecting data and analyzing them, we estimate them. 80/20 Thinking requires, and with practice enables, us to spot the few really important things that are happening and ignore the mass of unimportant things. It teaches us to see the wood for the trees.
