     We do some strange things when we don't like the way our life is going. Too often we blame(埋怨)

someone else.

     "I wish my parents were more understanding."

     "I have such a bad Chemistry teacher!"

     "My friends are so boring and self-centred. They make my life worse and worse."

     Blame! Blame! Blame!

     It seems natural to sing this self-pitying song, but the truth is, if you don't like your life, you should do

something about it. No one else knows exactly how  you feel or what you need.  No one can read your

mind correctly. You are the only one with the  power(能力) to  check your life, and if you want it to be

different, you can change what you're doing. This means asking.. "What do I need? What do I want to

do?" instead of trying to meet others'  needs. For example,  try  to  decide how you want to spend your

evening instead of asking somebody else for advice. We teach other people how we want to be treated.

If we don't think of our own needs, no one else will either.

     When you're in trouble, don't give away your power to decide how you feel about yourself. Choose

how you want to think and act(行动). Other people can't make you unhappy or angry. They only act in

their own way and then it's up to you to decide how you will respond(回应). For example, your friends

go out to lunch withou t you.  You feel angry.  How are you going to act?  You may blame your friends.

"They're not kind. Who needs  them anyway?"  or  you may tell your friends how you feel, listen to their

explanation(解释), and let them know you'd like to be invited next time.

     When you decide everything in your own way,  you're  getting  hold  of your own life and shaping it

according  to  your tastes  and feelings.  You can  choose to be happy, to make friends and to build an

interesting life. When you blame others for what is  or  isn't  happening  in  your life,  you have stopped

growing or learning.

     One of the most important rules is that  you  can  never  change another person by your direct action.

The only person you have the right and power to change is yourself. Once you change, the other person

then has something different to respond to and change is possible. If you  want change in your life, begin

with yourself...put love into your power to take action.
