A bird in the hand is worth two in the bush
It states a truth which is very obvious. In fact, it understates the truth. A bird in the hand is better than any number of birds in the bush. However, we have to admit that the statement is too realistic and that for higher achievements, one has sometimes to sacrifice the immediate gains. The risk a businessman has to take is very obvious. His eye is more on the distant gain than on immediate profit. He seems to prefer the two birds in the bush to the one in hand. But, generally speaking, the best policy is to keep the one in the hand and also strive to get the other two that are in the bush.
