From : Peculiar Habits of Incredibly Successful People

Adams writes in his book How to Fail at Almost Everything:

A system is something you do on a regular basis that increases your odds of happiness in the long run. If you do something every day, it's a system. If you're waiting to achieve it someday in the future, it's a goal.

The system-versus-goals model can be applied to most human endeavors. In the world of dieting, losing twenty pounds is a goal, but eating right is a system. In the exercise realm, running a marathon in under four hours is a goal, but exercising daily is a system. In business, making a million dollars is a goal, but being a serial entrepreneur is a system.

President Obama wears the same style suits to reduce low-level decision-making

He explained in 2012:

You'll see I wear only gray or blue suits. I'm trying to pare down decisions. I don't want to make decisions about what I'm eating or wearing. Because I have too many other decisions to make. You need to focus your decision-making energy. You need to routinize yourself. You can't be going through the day distracted by trivia.

Charles Darwin tried his whole life to prove his own theories wrong

Charlie Munger once explained Darwin's philosophy:

One of the great things to learn from Darwin is the value of the extreme objectivity. He tried to disconfirm his ideas as soon as he got 'em. He quickly put down in his notebook anything that disconfirmed a much-loved idea. He especially sought out such things. Well, if you keep doing that over time, you get to be a perfectly marvelous thinker instead of one more klutz repeatedly demonstrating first-conclusion bias.
