Investment success doesn’t come from "buying good things", but rather from "buying things well". - Howard Marks

A high-quality asset can constitute a good or bad buy, and a low-quality asset can constitute a good or bad buy. The tendency to mistake objective merit for investment opportunity, and the failure to distinguish between good assets and good buys, get most investors in trouble.

o In bubbles, infatuation with market momentum takes over from any notion of value and fair price, and greed (plus the pain of standing by as others make seemingly easy money) neutralises any prudence that might otherwise hold sway.

If you've settled on the value approach to investing and come up with an intrinsic value for a security or asset, the next important thing is to hold it firmly. That's because in the world of investing, being correct about something isn't at all synonymous with being proved correct right away.
