It happened that a fisher, after fishing all day, caught onlya little fish. "Pray, let me go, master," Said the fish. "I ammuch too small for your eating just now. if you put me back intothe river I shall soon grow, then you can make a fine meal offme." "Nay1, nay, my little fish," Said the fisher, "I have you now.I may not catch you hereafter." 
A little thing in hand is worth more than a great thing in prospect2.
