Unlike simple algebra, the problem of life has multiple right solutions. Our task is simply to avoid the wrong decision. That is the idea of Charlie Munger’s mental model.

And it is simply applicable to almost life aspects.

In investing, you don’t need to choose the best stock or the most stellar company. You just need not invest in bad companies.
