The most intelligent person is one who humbly accepts the ideas of others, and not their own

Try stuff. I also used to believe that it's better to be smart than lucky because if you're smart you can out-think the competition. I don't believe that anymore--this is not to say that you should strive for a high level of stupidity. My point is that luck is a big part of many successes, so (a) don't get too bummed out when you see a bozo succeed; and (b) luck favors the people who try stuff, not simply think and analyze. As the Chinese say, "One must wait for a long time with your mouth open before a Peking duck flies in your mouth."
