Happy life lies in a peaceful mind.
幸福的生活存在于心绪的宁静当中。
What can be seen as happy life?
Maybe the answer is various for different people.
Even for the same person, his answer may be different while his age or his experience changes.
Suddenly, I recalled some words I had seen in the signature of one friend, a girl that can be called my goddness:
Happy life is actually very simple, there's someone who loves you, there's something you can do, and there's something you can expect.
Quite right.
You change your life by changing your heart.
你转变了心意，便改变了生活。
You are what you think of.
Change your thoughts first, then through your actions you will change your life.
But don't be impatient and give up your efforts if you haven't seen the changes yet.
Because change itself is a long process. Don't expect to get instant results.
