7 Mistakes to Avoid???

Some good sharing on what i read. In a lot of ways investing is like badminton match in our recent Thomas Cup 2010. In badminton, having a killer serve or smash technique will win you a lot of points. But it does not mean you are the winner at the end of the day. It's often the player with the least mistakes who wins ;)

Below are some of the temptations:
1. Swinging for the fences - buy great company with economy moats. Do not load portfolio with risky and swinging for the fences on every pitch.
2. Believing that it's different this time - example year 2000 on semiconductor stocks.
3. Falling in love with products
4. Panicking when the market is down
5. Trying to time the market
6. Ignoring valuation
7. Relying on earning for the whole story
