We are conditioned to want to be richer; we are trained to want the latest style that television tells us; we want to earn more money because then we'll have a good life.But none of that will make us happier. And the sad thing is that it can take us decades of pursuing(追求)wealth and expensive things before we realize that. So what will bring ushappiness? Luckily, there are three things that don't cost anything. Here they are:Good relationships. We have a human need to be close with other human beings. Having good, supportive friendships, a strong marriage or loving relationships with our family members will make us much more likely to be happy. Therefore, take time, today, to stay with your loved ones, to tell them what they mean to you, to listen to them, and to develop your relationships with them.Positive thinking.

In fact, this should be one of the first habits you develop.Flow. This is a popular concept on the Internet these days 一 the state we enter when we are completely focused on the work or tas^. Having work and leisure(休闲）that gets you in this state of flow will almost undoubtedly lead to happiness. People find the greatest enjoyment not when they're passively mindless, but when they're absorbed in a mindful challenge.If you are interested in some kind of work and keen on some kind of hobbies, it is not a bad idea. Turn off the TV 一 this is the opposite of flow 一 and then go outside and do something that truly makes you active.
