Investment tips from John Bogle, founder of the Vanguard Mutual Fund

I have another surprise; John Bogle also agreed to speak to me about the stock market.
John Bogle is the founder and chairman of Vanguard Group, which he founded in 1974, and is also the author of ten books, including The Little Book of Common Sense Investing and The Common Sense on Mutual Funds. He is a strong advocate of long-term investment in mutual funds linked to indices.
