It is pretty incredible to think that 10 years ago we hit the low of the 2007, 2008, type market. And it's actually March of 2009 that we started this incredible journey higher. That all said, I think the biggest thing most people have learned is that we don't go straight up. Although if you look at the chart, it may look that way. There are a lot of hiccups in between. What does this really mean for you as an investor? The primary thing it means is not to put all your eggs in one basket. And what I mean by that is if you have 500 shares to buy. Maybe you think about buying 100 or 200 shares to start. The reason for that is so often we sell off. And movement can be your friend rather than your enemy. The biggest mistake I see most people make is they're all in or they're all out. When professionals invest, they really think in terms of small amounts because with small amounts, number one, they can make better decisions. And number two, if things move, suddenly it's your friend rather than your enemy. This is a nicer way to keep your cool and look at the market on a longer term basis.
