10 rules for building wealth

From FORTUNE

1. Start early



2. 401(k)



3. Keep it simple - invest index funds
   
   Most likely picking stocks isn't your full-time job.
   
   Choosing three or four index funds - such as, a S&P 500 fund, an EAFE fund, and a small-cap stock fund - will give you broad exposure.



4. Don't try to beat the market



5. Don't chase trends
   
   You want to grow your money for the long haul, so you don't switch your strategy every time you read the headlines.



6. Make saving automatic



7. Stocks in your portfolio should be (120 - age)
   
   And the rest should be in bonds



8. Minimize investment costs



9. Minimize credit card costs



10. Defer taxes as long as possible
