The way to become rich is to put all your eggs in one basket and then watch that basket.
Concentrate your energy, thought and capital exclusively upon the business in which you are engaged... 'Don't put all your eggs in one basket' is all wrong. I tell you 'put all your eggs in one basket, and then watch that basket.'
Concentrate your energies, your thoughts and your capital.... The wise man puts all his eggs in one basket and watches the basket.
Concentrate; put all your eggs in one basket, and watch that basket.
