To become a multi-millionaire: First, go to the stock exchange and sell 20% of your shares. Then increase your advertising budget to 1,265,000 and end the quarter. Your account should now be at least 5,000 in the red. Now go back to the stock exchange and sell all your shares. Then buy back 77% of your own shares. Your account balance will now jump to 987,840,156!

(If your own shares cost less than 1 million, it's best to buy back the remaining 23% as well.)
