Investing is the intersection of economics and psychology. The analysis is actually the easy part. The economics, the valuation of the business isn't that hard. The psychology - how much do you buy, do you buy it at this price, do you wait for a lower price, what do you do when it looks like the world might end - those things are harder. Knowing whether you stand there, buy more, or whether something has legitimately gone wrong and you need to sell, those are harder things. That you learn with experience, by having the right psychological makeup.

The way to maximize outcome is to focus on the process.

Investors frequently benefit from making decisions with less than perfect knowledge and are well rewarded for bearing the risk of uncertainty. The time other investors spend delving into the last unanswered detail may cost them the chance to buy into situations at prices so low they offer a margin of safety despite the incomplete information

It is important to remember that value investing is not a perfect science. It is an, with an ongoing need for judgment, refinement, patience, and reflection. It requires endless curiosity, the relentless pursuit of additional information, the raising of questions, and the search for answers. It necessitates dealing with imperfect information - knowing you will never know everything and that that must not prevent you from acting. It requires a precarious balance between conviction, steadfastness in the face of adversity, and doubt - keeping in mind the possibility that you could be wrong.

If an asset has cash flow or the likelihood of cash flow in the near term and is not purely dependment on what a future buyer might pay, then it's an investment. If an asset's value is totally dependent on the amount a future buyer might pay, then its purchase is speculation.

Do not suffer interim losses, relish and appreciate them

Value investors have to be patient and disciplined, but what I really think is you need not to be greedy. If you're greedy and you leverage, you blow up. Almost every financial blow up is because of leverage.
