根据短文内容,从下框的A-F选项中选出能概括每一段主题的最佳选项。选项中有一项为多余项。

A. Live below your means

B. Always stay positive

C. Educate yourself

D. Work towards a dream

E. Developing lasting personal relationships

F. Stay in shape

1.____________

We all want to buy that new piece of technology, treat ourselves to an expensive dinner, or take out a loan for the car we can't afford. It might feel great at the time but hasty(匆忙的)spending hurts a lot later on. Enjoy life's simple pleasures and save as much as you can. Expensive things don't create lasting happiness. Careful spending will bring you greater enjoyment in the long run.

2. _____________

To be happy we need continuous growth. The best way to grow is life-long education. This doesn't mean you need to pursue a doctorate or spend 2 hours reading every day. Self-education can be anything that takes you out of your comfort zone. The important part is keeping an open mind and searching for fresh ideas.

3._____________

Suppose you had everything you wanted. Would you be happy without anyone to share it with? The personal relationships we develop with friends and family members are the greatest source of happiness in our lives. Don't forget about them. Taking the time to develop and enjoy personal relationships is important to long-term happiness.

4._____________

Even if your life isn't perfect, you can always build toward a goal. The best way to do this is working towards a goal. We can’t control everything about our lives, but working towards a goal gives us something positive to focus on and lays the foundation for future success. No matter what your passion is, get out there and start doing something.

5._____________

You only get one body. Once it is ruined, there isn't much you can do about it. Exercise to keep the body working well. Avoid eating too much of damaging substances and unhealthy foods. It may feel terrible at the time but enjoying good health in your later years is worth the sacrifice.
