Tpic : What is the most common problem you have in your daily routine?

People have different personalities and living patterns, and those two things together can cause people to have different problems in their daily lives. Two of the common problems I have in my daily routine are my unhealthy sleep pattern and my careless personality. On the one hand, my abnormal sleep pattern is mostly caused by my bad time management, and lack of sleep has affected me negatively in many ways. On the other hand, my careless personality is rather a natural trait I have since I was born, and it also has caused a lot of problems in my life. Although those two problems are not too severe as they look, I believe, in the long term, that they are still quite the serious problems.

Unusual sleep pattern is one of the problems I have, and also many teenagers have in their daily lives. One of the reasons that cause this problem is bad time management. For instance, I always spend too much time on watching TV, or playing computer games, and leave only little time to do the important things, such as doing my homework or studying. Because I did not manage my time so well, I usually have to stay up very late to complete all the things I have to do. Consequently, on the next day in school, I usually can not concentrate well because of my lack of sleep. To cure this problem, I will begin to manage my time more wisely, and therefore, get to sleep earlier.

The other problem I have in my daily life is my careless personality, and it really bothers me in many ways. For example, when I am leaving from one place to the other, I often forget to bring my personal belongings with me. Sometimes I only lose pens or books, but sometimes I lose my wallet too. Another example of my careless behaviors is making a lot of careless mistakes in the tests. During the tests, although I was pretty sure that I understood all the materials on the tests, I still made a lot of minor, careless errors in the tests; therefore, I did not get the marks that I really deserved to have. Although my careless personality is quite hard to change, by paying more attention and being more careful, I can still make some improvements.

My unusual sleep pattern and careless personality are two of the common problems I have in my daily life. The former problem has resulted my poor performance in school and also my unhealthy condition. The later problem, my careless personality, has caused me to lose a lot of my belongings, and also has caused me to do badly in the tests. Although the ways to solve these two problems are different, being determined to solve them is still the key to make changes.
