How to improve our life? Many people think that they have to accept whatever life throws at them. They'll say, "This is my destiny. I cannot change it."

Of course not! You don't have to suffer needlessly. Your life depends on you, not on other factors.

I know a woman 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, and then goes to sleep. Next day, the same routine 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 has been intended for her and that her luck can only change if God wills it. She hasn't realized that we have to do our share of making the effort to live the life of our dreams.

Remember that you harvest what you sow. You have to get off the sofa, get your eyes off the TV screen, get your hands off the phone (unless it’s helpful to your success), and get your mind and body to work! 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(暂时的) problem; Instead, learn your lesson, make the most of the situation, and do something to solve the problem. It's not enough to think positively; you also have to act positively.

If someone's life is in 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.
