Time is the friend of the wonderful business. It's the enemy of the lousy business. If you're in a lousy business for a long time, you're going to get a lousy result, even if you buy it cheap. If you're in a wonderful business for a long time, even if you pay a little too much going in, you're going to get a wonderful result if you stay in a long time.
Warren BuffettWhen forced to choose, I will not trade even a night's sleep for the chance of extra profits.
