It is far more difficult... to know when to sell a stock than when to buy.
Don't speculate unless you can make it a full time job.
Become more humble as the market goes your way.
Making a success of the job at hand is the best step toward the kind you want.
We can't cross that bridge until we come to it, but I always like to lay down a pontoon ahead of time.
Even when we know what is right, too often we fail to act. More often we grab greedily for the day, letting tomorrow bring what it will, putting off the unpleasant and unpopular.
