Circle Of Competence

What an investor needs is the ability to correctly evaluate selected businesses. Note that word “selected”: You don’t have to be an expert on every company, or even many. You only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital.

Doing

Of the three main activities involved in scientific research, thinking, talking and doing, I much prefer the last and am probably best at it. I am all right at the thinking, but not much good at the talking.

– Fred Sanger

Reared For Immortality

The Constitution has been reared for immortality, if the work of a man may justly aspire to such a title. It may, nevertheless, perish in an hour by the folly, or corruption, or negligence of its only keepers, The People. Republics are created by the virtue, public spirit, and intelligence of the citizens. They fall, when the wise are banished from the public councils, because they dare to be honest, and the profligate are rewarded, because they flatter the people in order to betray them.
