We all know that money can't make us happy, but many times we act as if we'd be

happier with a bit more money. 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

us happiness? 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 r

elationships with them.

Positive thinking. Optimism(乐观) is one of the best indicators of people who lead a

happy life. Happy people feel empowered, in control of their lives. So why not make

positive thinking a habit? 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 task. 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.
