All investors must come to terms with the relentless continuity of the investment process.

Great investments don't just knock on the door and say "buy me".

It is crucial in a sound investment process to search a mile wide than a mile deep with they find something - also.. never stop digging for information.

Speculators are obsessed with predicting: guessing the direction of stock prices. Every morning on cable television, every afternoon on the stock market report, every weekend in Barron's, every week in dozens of market newsletters, and whenever business people get together. In reality, no one knows what the market will do; trying to predict it is a waste of time, and investing based upon that prediction is a purely speculative undertaking.

Value investors will not invest in businesses that they cannot readily understand or ones they find excessively risky. Hence few value investors will own the shares of technology companies. Many also shun commercial banks, which they consider to have unanalyzable assets, as well as property and casualty insurance companies, which have both unanalyzable assets and liabilities.

Always look for forced urgent selling.

In investing it is never wrong to change your mind. It is only wrong to change your mind and do nothing about it.
