     A 92-year-old lady moved into a nursing home (疗养院).  Although she was blind, her hair and clothes

  looked very nice.

      Her husband of 70 years old had recently passed away, so she had to move out of' her old house.

 After many hours of waiting patiently in the lobby of the nursing home, she smiled sweetly when I told her

 that her room was ready in the elevator, I began to describe her room.

       "I love it." she smiled with the excitemene of an eight-year-old girl who has just been presented with a

  new doll. "But you haven't seen the room. Just wait."

       "That doesn't have anything with it,"she replied. "Happiness is something you decide on ahead of

 time.  Whether I like my room or not doesn't depend on the furniture. It's how I arrange my mind,  I

 already decided to love it. lt's a decision I make every morning when I wake up.  I have two choices. I

 can spend the day in bed complaining of the parts of my body that no longer work, or get out of bed and

 thank the ones that still do.  Each day is a gift and as long as my eyes open,  I'll  focus on the new day and

  alI the happy memories in my life. Old age is like a bank account, You take out from what you've put

  in.  I am still patting in."

     If you want to be happy, please remember these five simple rules:

     Free your hcart from hate.

     Free your mind from worries.

     Live simply.

     Give more.

     Expect less.

    Then your happiness will increase everv day
