Today you will see Warren Buffett’s 5th rule of Investing.

5.Watch Small Expenses:

Warren Buffett invests in businesses run by managers who obsess over the tiniest costs. He once acquired a company whose owner counted the sheets in rolls of 500-sheet toilet paper to see if he was being cheated (he was). He also admired a friend who painted only on the side of his office building that faced the road. Exercising vigilance over every expense can make your profits — and your paycheck — go much further.
