Lack of knowledge is not always a disadvantage

My daughter Grace (3) could determine the color above faster than my son Rex (5).
It is simply because Grace can't read!

In real life some people have more guts than the others simply because they have lack of knowledge.
A friend of mine who is very smart could never be succeed because he always calculate every risk of his step. When you decide not to enter a new business, it means you will never be succeed on that field. In contrary if you just go in, you'll have the chance of either one, succeed or fail.
