While the individual man is an insoluble puzzle, in the aggregate he becomes a mathematical certainty. You can, for example, never foretell what any one man will be up to, but you can say with precision what an average number will be up to. Individuals vary, but percentages remain constant.

If you invested in a very low cost index fund - where you don't put the money in at one time, but average in over 10 years -you'll do better than 90% of people who start investing at the same time.
At age nine, I got a paper route. Sixty-six papers had to be delivered to sixty-six families every day. I also had to collect thirty cents a week from each customer.

The extraordinary woman depends on the ordinary woman. It is only when we know what were the conditions of the average woman's life - the number of children, whether she had money of her own, if she had a room to herself, whether she had help bringing up her family, if she had servants, whether part of the housework was her task - it is only when we can measure the way of life and experience made possible to the ordinary woman that we can account for the success or failure of the extraordinary woman as a writer.

Government is merely an attempt to express the conscience of everybody, the average conscience of the nation, in the rules that everybody is commanded to obey. That is all it is.
An inventor's endeavor is essentially lifesaving. Whether he harnesses forces, improves devices, or provides new comforts and conveniences, he is adding to the safety of our existence. He is also better qualified than the average individual to protect himself in peril, for he is observant and resourceful.
Pay no heed to the average photographer's remarks upon "flat" and "weak" negatives. Probably he is flat, weak, stale, and unprofitable; your negative may be first-rate, and probably is if he does not approve of it.
Investors... can't pick stocks that are better than average. Stocks are a good thing to own over time. There's only two things you can do wrong: You can buy the wrong ones, and you can buy or sell them at the wrong time. And the truth is you never need to sell them.
