The stock market is filled with individuals who know the price of everything, but the value of nothing.

My mistake was to project my skill beyond the limits of experience. I began investing outside the industries which I believe I thoroughly understood, in completely different spheres of activity; situations where I did not have comparable background knowledge.

I had made what I believe was one of the more valuable decisions of my business life. This was to confine all efforts solely to making major gains in the long-run.

Practical investors usually learn their problem is finding enough outstanding investments, rather than choosing among too many.

Of one thing the investor can be certain: A large company's need to bring in a new chief executive from the outside is a damning sign of something basically wrong with the existing management - no matter how good the surface signs may have been as indicated by the most recent earnings statement.

The successful investor is usually an individual who is inherently interested in business problems.
