For example: Many people try to eliminate randomness. They look for steady solutions to lifelong problems: Marriage, long-term job, owning a house, stuff like that. Sometimes it works, sometimes it doesn't.

actually from the rates of divorce and unemployment it shows that it often does not and rarely does work :)

I found playing lots of poker and studying that game when I was young to be a very useful way to learn more about statistics and randomness.

i think with poker you learn much more about human behavior.
