Chinese people often say: have a grateful heart....(bad translation, ie.being grateful)
Always thank people who help you. Though sometimes you think he doesn't help you, try to be grateful for everything.
It also involves that we'd better think positively.
It's easy to say than done. Especially when we deal with close friendship, family membership....we require more, we complain more, we seldome praise, or forgot to praise.
Being grateful, it's what i have to bear in mind.
