Let me tell you about five of the enemies we face from within．The first enemy that you’ve got to destroy before it destroys you is indifference．What a tragic disease this is! “Ho-hum，let it slide. I’ll just drift along．” Here’s one problem with drifting：you can’t drift your way to the top of the mountain．
The second enemy we face is indecision(优柔寡断). 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．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． , they doubt themselves．I’m telling you，doubt will destroy your life and your chances of success．It will empty both your bank account and your heart．Doubt is all enemy．Get rid of it．
The fourth enemy within is worry．We’ve all got to worry some．Just don’t 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’ve got to worry．But you can’t let worry loose like a mad dog that drives you into a small coffer．Here’s what you’ve got to do with your worries：drive them into a small corner. Whatever is out to get you，you’ve got to get it．Whatever is pushing on you, you’ve got to push back．
The fifth enemy is overcaution. It is the timid (胆小的) approach to life．Timidity is not a virtue；it’s all illness．If you let it go，it’ll conquer you．Timid people don’t get promoted．They don’t advance and grow and become powerful in the marketplace．You’ve got to avoid overcaution．
