Right from childhood, Buffett was fond of making money. He involved himself in many door to door selling campaigns and also worked in a grocery store owned by his grand father. When he was in high school, he teamed up with one of his best friends and purchased a second-hand pinball machine. Together they placed it in a barber’s shop and with that residual income they slowly started to buy several such machines and placed it in other barber shops. Buffett’s interest in stock market sprouted at a very young age, when he spent hours in the customer’s lounge of a nearby stock brokerage company. He was only ten, when he planned to visit the New York Stock Exchange. In his high school days, he purchased City Service shares for himself and his sister. When he completed his graduation, Buffett had more than 90,000USD in his savings account.
At only six years old, Buffett purchased 6-packs of Coca Cola from his grandfather's grocery store for twenty five cents and resold each of the bottles for a nickel, pocketing a five cent profit.
