     Attitude is one of the most important factors in determining success for all people. Successful people have

one thing in common-an expectant (期待的) attitude of success. Most people begin each morning in neutral

and react to events of the day. You can be one of the successful people in life by starting each day with a

positive attitude, a gratitude for the opportunities you have, and an expectancy (期待) of the best for yourself.

     People tend to live up to expectations. We get out of life just about what we put into it. Our environment

becomes a mirror of our spirit, our attitude, and expectations. If we set a great goal, we get great results. If

we have a fair goal, we accomplish fair results, and if we have a poor goal, we accomplish poor results. The

world will give you back what you expect, so expect the very best. Don't be defensive or doubtful. Nothing

changes unless you do. Before you can do something, you've got to be something. Know that you have worth

and value. Show that to the world.

     Treat everyone you come in contact with as the most important person in life. It will build self-esteem (自

尊心). Smile! You'll be rewarded with a returned smile. Don't react to others rudely. Forgive everyone who

ever hurt you. Then, forgive yourself. Keep yourself healthy. Exercise. Eat a proper diet. Display an attitude

of confidence.

     Develop these good habits and your expectancy will be rewarded by successes. This attitude will put you

into that group of people who are truly successful, because you will know and understand how an expectant

attitude enhances (提高) every aspect of your life.
