天天向上课时同步训练系列答案
阳光课堂同步练习系列答案Many people often lose their chance to live life to the fullest because of procrastination, which means that they always delay（拖延）doing something that must be done at once. Moreover, because they often put off their plans till “tomorrow”, they are less likely to achieve their goals and will give up their dreams and goals finally. As a result, we can say that procrastination is the enemy of a progressive lifestyle.
Now that we know procrastination is something bad, why do some people not take immediate action? Well, there are some things that result in procrastination. Depending on someone else rather than doing by oneself is one of the things. Whenever you wait for something to happen before you act, you make it easier to delay your goals and dreams until “someday”. Another cause of procrastination is that people do not value each moment in their day. Actually, it’s surprising how much you can do if you just decide to do little things with the little time you have. Also those who often procrastinate can always find a good reason for something they refuse to do at once.
If you are one of those who often delay, then it’s time for you to make a decision to act now because things happen only when we decide to act. Get down to doing something like losing weight, saving money or spending more time with family. Don’t let these things continue to be a desire（欲望）for you to do “someday”, but make a decision to do it now.
Once you have made your decision, write down the plan and take action immediately. Making plans can help you think carefully about how you are going to do what you need to do. After understanding how to do what you want to do, get doing with the plan. It doesn’t matter how small the move you make is as the little things you do accumulate（累积）over time and move you to be closer to your goals. So, don’t wait until tomorrow; instead, start now! Just make use of every moment you have to do something that is helpful in realizing your dreams and goals.
Here is a challenge that will also move you to be closer to your dreams and goals if taken seriously. Make a list of ten things you have been putting off. It could be anything from getting a health examination, calling a friend or family member, to getting the car fixed and cleaning out the garbage, etc. And then try to develop the habit of doing them immediately!
