The capacity of the human mind for formulating and solving complex problems is very small compared with the size of the problems whose solution is required for objectively rational behavior in the real world.

Every breakthrough is at first laughable and ridiculous. In fact if it did not start out laughable and ridiculous， it is not a breakthrough.

面临大事与难事，可看出一个人的责任；处顺境逆境，可看出一个人的胸襟气度；遇喜事怒事，看一个人的涵养；与同辈相处，可看一个人的见识。

人生は、一度きりの旅だ。
