Hello, everybody. I am happy to introduce our respectable speaker for today’s lecture, Dr. Lincoln Duncan. Dr. Duncan, Professor of Psychology at Harvard University, has written numbers of articles and books on the topic of enemies for the recent years, he says in his books that everybody should admit having enemies, no matter how humble and generous they are. OK. Let’s welcome, Dr. Duncan.
Dr. Duncan: Hello, everyone. First answer my quick question: have you got an enemy in your life? Most of you may say yes. But you may misunderstand what I really mean. The enemy we are talking about today is the one inside your heart.
We are not born with courage, but neither are we born with fear. Maybe some of our fears are brought on by our own experiences, by what you’ve read in the papers. Some fears are valid, like walking alone in a bad part of town at 2 o’clock in the morning. But once you learn to avoid that situation you won’t need to avoid that situation, you won’t need to live in feat of it. Fears, even the most basic ones, can totally destroy our ambitions. Fear can destroy fortunes. Fear can destroy relationships. Fears, even the most basic ones, can totally destroy our ambitions. Fear can destroy fortunes. Fear can destroy relationships. Fear, if left unchecked, can destroy our lives. Fear is one of the many enemies lurking（潜伏） inside us.
The second enemy we face is indecision(犹豫不决). Indecision is the thief of opportunity and enterprise. It will steal your chances for a better future. Take a sword to this enemy.
The third enemy inside is doubt. Sure, there’s room for healthy skepticism（怀疑）. You can’t believe everything. But you also can’t let doubt take over. Many people doubt the past, doubt the future, doubt each other, doubt the government, doubt the possibilities and doubt the opportunities. Worse of all, they doubt themselves. I am telling you, doubt will destroy your life, and your chances of success. It will empty both your bank account and your heart. Doubt is an enemy. Go after it. Get rid of it.
The fourth enemy within is worry. We have all got to worry about something. Just do not let it conquer you. Instead, let it alarm you. Worry can be useful. If you step off the curb（路边） in New York City and a taxi is coming, you have got to worry. But you can’t let worry loose like a mad dog that drives you into a small corner. Here is what you have got to do with your worries: drive them into a small corner. Whatever is out to get you, you have got to get it. Whatever is pushing on you, you have got to push back.
The fifth interior (内在的）enemy is over-caution（小心过头）. It is the timid approach to life. Timidity （胆小）is not a virtue; it is an illness. If you let it go, it will conquer you. Timid people don’t get promoted.They do not advance and grow and become powerful in the marketplace. You’ve got to avoid over-caution.
Do battle with the enemy. Do battle with your fears. Build your courage to fight what’s holding you back, what’s keeping you from your goals and dreams. Be courageous in your life and in your pursuit of the things you want and the person you want to become. Hope you enjoyed today’s talk. Thank you!
