35 Quotes That Changed How I Think About Investing

It looks like the market will end the year up more than 30 percent. This will make 2013 the seventh-best year for stocks in the last half-century.

If you're an investor, congratulations. The pundits have spent the last five years predicting doom and gloom. In the meantime, they've missed one of the largest stock market rallies in history. Those who try to avoid market losses by sitting on the sidelines consistently end up missing even larger gains. That's why patient, long-term investors win out in the end.

I have no idea what 2014 will bring. But even after this year's rally, I don't think all the opportunity is behind us. I'm as confident as ever that buying good businesses held for the long haul is the surest way to build wealth.

I'm a fan of short, pithy wisdom. You can often gain more insight in a single sentence than you can in a whole book. So here are 35 quotes from famous investors and thinkers that changed how I think about investing.
