Graham: Smallest Possible Sums

"There is a great advantage for the young capitalist to begin his financial education and experience early. If he is going to operate as an aggressive investor he is certain to make some mistakes and to take some losses. Youth can stand these disappointments and profit by them. We urge the beginner in security buying not to waste his efforts and his money in trying to beat the market. Let him study security values and initially test out his judgment on price versus value with the smallest possible sums." - Benjamin Graham
