A Quote by James O'Shaughnessy

Historically, we have always seen reversion to the mean. After stocks have had an unusually great 10 or 20 years, they typically turn in subpar results over the next 10 or 20, and after bad 10- to 20-year stretches, the next 10 to 20 tend to be above average.
There were three terrible ages of childhood - zero to 10, 10 to 20, and 20 to 30.
You can put a person in jail for 5 years, for 10 years, or 20 years, for the same crime. We're deciding on 10 years to 20 years, when 5 years would be enough. Okay. The deterrent value, the additional amount of leverage that you get over a criminal to keep them from breaking the law in the first place, associated with making the sentences longer, is de minimous; it's essentially nothing.
There are three terrible ages of childhood - 1 to 10, 10 to 20, and 20 to 30.
Just because you are embarrassed to admit that you're still living the consequences of bad decisions made 5, 10, 20 years ago shouldn't stop you from making good decisions now. If you let pride stop you, you will hate life 5, 10, and 20 years from now for the same reasons.
I'm really interested in working with groups. It's a very simple thing for me, and if I'm given the option to work with two people or 10 or 20 people, I'm going to take 10 or 20. I just think there's so much more I can do with that.
We have made a commitment to feed 20-million people over the next two years. We are somewhere around 10 million. But I can promise you that we are not going to stop at 20 million. Because hunger, there is almost no cure for it. You can take care of the problem today, but it is a recurring problem.
I have been working since I was 20, and I'm 38. I actually once averaged out what I had made over my professional life. I think I could have made that much as a waiter or an insurance salesman. You know, I spent so many years in my 20's making $10,000 a year.
In giving presentations, use the 10/20/30 rule....use only 10 slides, take 20 minutes maximum, and use at least 30-point fonts.
See that fella over there? He's 20 years old. In 10 years, he's got a chance to be a star. Now that fella over there, he's 20 years old, too. In 10 years he's got a chance to be 30.
What's got me excited about the education space is the growth of the Internet over the next 10, 20, 30 years.
Every 10-15 years, society changes. The thinking of a 10-year-old kid changes when he turns 20. Such changes can be seen in every aspect of life. People's preferences also change with time.
We don't have great answers to what jobs will look like in 10, 20, 30 years. And I think it's right for people to have some anxiety in a world where driverless cars are going to take over. Like, how are you going - it's gotten really, how are you going to have a job in 10 years, and how are your kids going to have a job in 10 years, if you haven't gone to college or had a lot of hand-ups in the system, basically.
I think that no one, or very few, are born as good presenters. It's a skill that you learn. The key is the 10/20/30 rule: 10 slides given in 20 minutes using no font smaller than 30 points. If people just adhered to this rule, they would double or triple the quality of their presentations.
In Turkey it was always 1952, in Malaysia 1937; Afghanistan was 1910 and Bolivia 1949. It is 20 years ago in the Soviet Union, 10 in Norway, five in France. It is always last year in Australia and next week in Japan.
I played 'Mortal Kombat' competitively in arcades. Played for money at 10, hustling the 20-year-olds. Five bucks on whoever wins. Which, at 10 years old, is real money.
If you're going to do a memoir, then it's sort of at this age - in your late sixties or seventies - that you do it. I don't understand people who do memoirs when they're 20. I think most people need a little more time than 20 years to become the person they are. In fact, that process of becoming who you are is still ongoing when you get older, where you go, "Let's see where my next 10 years is going to take me." S
