Google published the top search queries in 2007, in English, "what is love" is the most hot question in "what is ?" section. Here is the link: http://www.google.cn/rebang/yuedu/2007.htm. Unfortunately, I found that I really don’t know what is love now, who can tell me, what is love? I thought that I know what is love, and what is happiness, and I really do the right thing to get love, love others, and pursuit of happiness, but seems like I lost in the race, I can’t define what is love and what is happiness now. Happiness is not own much money, I have enough money now, but I felt that I lost more things. Happiness is not in a great place, work with great people, I’m working at a best company now, I still felt I’m useless, I made no valuable things ever. Happiness is? I don’t know, I can only give some answer that happiness is not.

Here is an other article that teach you how to love your life: http://howtoloveyourlife.com/dothe/rightthing/main_text.html, I think that many words are useful, although many sentence I’ve used to instruct others, maybe, I’m the real one who most need these.
