Figuring out what you should do as an investor isn’t that difficult. You can read all Warren Buffett has written or said over the years, for example, and basically emulate that. The hard part is to have the discipline and the patience to execute. The bottom line is that to be a good investor you need to only buy when it’s emotionally the hardest, only sell when it’s emotionally the hardest, and do pretty much nothing while waiting for market extremes to offer opportunities to do either. That’s all incredibly hard. You often don’t know you’ve been right until months or even years later. Most people need more immediate gratification than value investing typically offers up.
