X房地产开发企业通过"招拍挂"取得一宗土地开发权，该土地性质为住宅用地，项目开发周期为3年。该房地产企业委托一家咨询公司对本项目的市场、方案、效益和风险等进行分析。（1）甲咨询工程师设计了3个互斥开发方案，并依据可比性原则，采用动态分析方法对各方案进行了经济效益比较。（2）乙咨询工程师采用专家调查法预测了3年后的住宅售价平均值：乐观值为7500元／m，悲观值为4000元/m，最可能值为5500元／m。（3）丙咨询工程师通过敏感性分析得知项目效益对住宅价格很敏感，当住宅平均售价为5200元/m时，项目的内部收益率等于开发商期望的最低回报率（12%）。丙咨询工程师分析了不同的住宅售价及其发生的概率，见表4-86。

Do you want to be the perfect you? When you are ready to improve yourself, give yourself a challenge. Challenge is the key to one’s growth. Try doing something that you are afraid of. When you get over your fears, the feeling of confidence in yourself can push you to new heights.
It is important to realize that habits are not easy to break. Just because setting your mind to do something does not mean you will be able to change it right away. Sometimes you may find yourself going back to what you’re used to. Don’t let this stop you from making the change you want.
If you aren’t sure where to start or what to change, imagine that you have to explain to someone in authority(权威) what you would need to do to develop or progress. If you have to, write it down and think about what you would say to make someone else believe that you are on the right path. This will help you be clearer about what you want to accomplish.
Figure out what you want to do with yourself. This doesn’t mean that you need to map out your entire life in advance. Consider the next five years. Where do you want to be? What does your life look like? If you evaluate(评价) yourself properly, you can decide on the best course of action to get where you want be.
Learn to value what is the best in your life. When value something, you naturally want to do whatever you can to achieve it. What you value influences the choices you will make in life. So if you value the best in your life, the activities that you choose will work toward achieving the best in your life.
Increasing your personal satisfaction with life is sometimes as easy as learning to give back to the community(社区)around you. Giving selflessly and donating charitably(慷慨地) is an excellent way to increase your own feelings of self-worth. Moreover, giving selflessly is an excellent way of proving your worth in your community.
Hopefully with all of the information you have just learned, you can start taking some serious steps toward your personal development. Remember that it is one thing to want to do something, but it is another thing to actually do it, so trying your best to do what you think is going to be right for you in your personal development goals.
