Attitude isn’t quite everything when it comes to being successful, but attitude plays a part in every stage of your life. A poor attitude gets more people fired than any other single factor, and a good attitude gets people jobs and helps them keep those jobs more than any other factor.
Your attitude affects many people, from your family to the stranger on the street corner. Your attitude is particularly important when you face seemingly hopeless situations. Losing a job or a friend because of a poor attitude is unfortunate—especially because a bad attitude can be fixed.
You can find at least two ways to look at everything. A pessimist looks for difficulty in the opportunity, while an optimist looks for opportunity in the difficulty. A poet of long ago put the difference between optimism and pessimism(悲观主义) this way: two men looked out of the prison bars—one saw mud while the other saw stars.
Unfortunately, many people look only at the problem and not at the opportunity that lies within the problem. Many employees complain about the difficulty of their jobs, for example, not realizing that if the job was simple, the employer would hire someone with less ability at a lower wage. A small coin can hide even the sun if you hold the coin close enough to your eye. So when you get too close to your problems, to think objectively(客观地) about them, try to keep in mind how your vision（视觉）can be obstructed. Take a step back, and look at the situation from a new angle.
You can’t do anything to change the fact that a problem exists, but you can do a great deal to find the opportunity within that problem. You’re guaranteed a better tomorrow by doing your best today and developing a plan of action for the tomorrows that lie ahead. Just remember to maintain a positive mental attitude.
