Janie was only searching for love and happiness, but isn't it that what everyone is searching for?, some people look for money as their first interest but when they get it... are they really happy, I think that what a person wants for life has changed in the past years, because from what I read and what I heard I know people used to search for happiness, and love, and they could find it in small things like playing in the park, or looking at the starts, or just with being with friends and family; but now no one is happy with what they have they people always want more, people is "unhappy" because they have responsibilities and they get lazy to do them. And with love everything has change too, in the past years  people used to have longer relationships, and sex was not only about pleasure it was about love, now it is all different no body really appreciates what real love is, everyone wants everything easy. Every one only wants money and power. As we can see like in the novel Janie was happy when she finally find a person she loved, in the inside of every person I think it is the same because, you can have lots of money and power, but you will only be happy when you will be surround by the people you love :D
