Scope
* Initial planning is the most vital part of a project.  A review of many failed projects indicates the disasters were well planned to happen from the start    
* Nothing is impossible for the person who doesn't have to do it    
* At the heart of every large project is a small project trying to get out    
* The most valuable and least used word in a project manager's vocabulary is "NO"
* When you find yourself in a hole, stop digging
 
Time    
* You can force someone into committing to an impossible deadline, but you cannot force someone to meet it    
* Tasks progress quickly until they become 90 percent complete and then remain at 90 percent forever    
* A project becomes a year late one day at a time  

Quality     
* The nice thing about not planning is that failure comes as a complete surprise, rather than being preceded by a period of worry and depression    
* A change freeze is like the abominable snowman; it is a myth and will always melt when heat is applied    
* While there never seems to be enough time to do it right the first time, there always seems to enough time to do it again    
* If you don't know how to do a task, start it, then ten people who know less than you will tell you how to do it 

Cost    
* The same work under the same conditions will be estimated differently by ten different estimators or by one estimator at ten different times    
* Any project can be estimated accurately, once it's completed 

Human Resources    
* Most managers succeed on the skills and strength of their staff    
* If you don't stand for something, you'll fall for anything    
* Too few people on a project can't solve the problems and too many create more problems than they solve    
* A comfortable project manager is one waiting for the next assignment    
* Everyone asks for a strong project manager, but when they get one they don't want one 

Communications    
* If it looks like a duck, walks like a duck, and quacks like a duck, it probably is a duck    
* A user will tell you anything you ask, but nothing more    
* Of several possible interpretations of a communication, the least convenient is the probably the correct one    
* A working meeting has about six people attending. Meetings larger than that are only for information transfer    
* I know that you believe that you understand what you think I said, but I am not sure you realize that what you heard is not what I meant 

Risk    
* Wrong decisions made early can be recovered from. Right decisions made late cannot correct them    
* The more you plan the luckier you get    
* If you don't attack the risks, the risks will attack you    
* What you don't know hurts you    
* The most valuable and least used phrase in a project manager's vocabulary is "I don't know"  

Etc. 
* Murphy is alive and well - and working on your project 
* The conditions attached to a promise are forgotten, only the promise is remembered
* * If it's not on paper - it wasn't said
