Warren Buffer's tips for investor
 
1. Look at stock as part of businesses. Ask yourself "How would I feel  if stock market is closing tomorrow for the next 3 years?" If i am happy  owing the stock under that circumstances, i am happy with business.  That frame of mind is important to investing. 2. The market is  there to serve you and not to instruct you. It's not telling you whether  you are right or wrong. The business result will determine it. 3.  You can not  precisely know what a stock is worth, so leave yourself a margin of  safety. Only go into things where you could be wrong to some extend and  come out OK. 4. Borrow money is most common way that smart guy go broke. 5.  The stock does not know you own it. You have feelings about it, but it has  no feeling about you. The stock doesn't know what you paid. People  shouldn't get emotional involved with their stocks.
