Warren Buffetts Rules for Investing Success

1. Ascertain the true quality of a company and its top managers.
2. Stockholders are not managers. They should leave the running of the firm to competent managers with integrity.
3. Don't invest in businesses you don't understand.
4. Give help and advice if they want it, but let the managers make their own decisions.
5. Never, ever break the law.
6. Owners are owners and managers are managers - but they should work as partners
7. Keep your distance from the market. You will understand the business better !
   

Theodore Levitt on Data
