The Tao of Investing : Ken Fisher of Fisher Investments (Fee Only Asset Management)

1. Always manage to a benchmark - else, how do you know how well you've done? KF uses MS World Index. It's your roadmap and choice set. For each stock, evaluate expected return and risk - to decide how much to own. Your biggest bet might be NOT owning British stocks when they are 10% of the world.
2. Always pose the question "What if I'm wrong?" and plan accordingly. Growth/Value. 
3. Build insurance into your investments - use negatively correlated items. When your stock is making new highs or is over-extended, consider buying a protective put. What put to buy? Remember that in a bear market, small caps fall much more than big stocks!
4. Don't worry about what the consensus fear is. The market will usually do something that no one is worrying about.
5. GM and US Steel : Examples of management squandering advantage of market dominance.
6. You make the most money with the least risk in small, well-managed companies aimed at big fast-growing markets. Right? WRONG! Long-term risk/reward is maximized by investing in companies aimed at markets appropriate to their size. I learnt size-segmentation the hard way. Small outfits have a long fight against Apple. Remember the parable of the lion and the mouse!
7. Chartered : $12-->$2. Storage Tech. System Industries - all bloopers. 
8. How to lose money : Overpay, buy businesses you don't understand and neglect to take a long-term approach.
9. Buy unpopular stocks of good companies!
10. Small-caps beating bigger companies? First sign of a bear-market counter-trend rally.
11. When you read an annual report, start at the back with the footnotes to the financials, then move forward. That's where they hide the bad stuff they didn't want to disclose but had to.
12. Successful investors are because of what they don't do - don't chase the trend-du-jour : hi-tech, emerging markets (tell me about getting burned by EUROX!), IPO's and trendy eateries (who can forget Shake Shack:)
13. Beware of the natural human proclivity for collecting. Have a museum, not a warehouse!
14. "Fed chairmen take a pill that lets them forget everything they ever knew and it lasts until the job is over."
15. Bear markets also have corrections. In an overall bear, the bear-market does occasionally reverse trend sharply for a few weeks or even months. Avoid buying into a relative high before market craters!
16. Keep an eye on foreign markets - you could have foretold the 1929 crash by looking at foreign bourses.
17. Buy to the sound of cannons, sell to the sound of trumpets.
18. When the market rebound from a bear market, most of its gains will happen in a very short time (< 2 mo)
