Only liars manage to always be out during bad times and in during good times.
Don't speculate unless you can make it a full time job.
Whatever failures I have known, whatever errors I have committed, whatever follies I have witnessed in private and public life have been the consequence of action without thought.
Most of the successful people I've known are the ones who do more listening than talking.
It is far more difficult... to know when to sell a stock than when to buy.
Don't try to buy at the bottom and sell at the top. It can't be done except by liars.
