投资者应警惕高费用和复杂的产品。

People are curious. A few people are. They will be driven to find things out, even trivial things. They will put things together, knowing all along that they may be mistaken. You see them going around with notebooks, scraping the dirt off gravestones, reading microfilm, just in the hope of seeing this trickle in time, making a connection, rescuing one thing from the rubbish.

The best thing a human being can do is to help another human being know more.

宇宙不仅比我们想象的更奇怪，而且比我们能够想象的更奇怪。
