    How to improve my life? Many people think that they have to accept whatever life throws at them. They'll say, “This is my fate, my destiny(命运). I cannot change it.”  Of course not! You don't have to suffer needlessly. Your destiny depends on you, not on any other outer factors.

    I know someone who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is? She wakes up in the morning, goes to work, comes back home, relaxes, chats with people, watches TV, then goes to sleep. Next day, the same things cycle follows.

    Huh! Is this what she calls “doing her best”? She believes she has tried her best and just accepts it in her heart that this is the life that God has intended for her to live; that her luck can only change if God wills it. Of course God wants us to be happy and live our life to the fullest, but we have to do our share of exerting (运用) the effort to live the life of our dreams.

    Remember that you reap(收获) what you sow. You just don't sit around and wait for a million dollars to fall from the sky. You have to get off the couch, get your eyes off the TV screen, get your hands off the phone. Don't expect your luck to change unless you do something about it. If something goes wrong, don't just regard it as a temporary(临时的) setback; but use it as feedback. Learn your lesson, make the most of the situation, and do something to solve the problem. It's not enough to think positively(积极地); you also have to act positively.

    If someone's life is in the trouble, do you just hope and pray that things will turn out fine? Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, don't just stand (or sit ) there, do something to improve your life.
