When some people become the university students, they always want to have a bright future, a good job afterwards. At school, someone studies so hard that they are called as "the bookworms". Someone else, on the contrary, they don't attend their study and they must retake some tests. In my opinion, the life of the full time university students needs the balance: they should spend most of the time studying, besides, they also need be doing other activities: Firstly, after the stressful studying hours, the students need be reproduced their moral strength. They need to spend time on physical activities by doing exercises, playing sport, joining camping... Speding a little time which scheduled reasonably for these activities not only doesn't make their power of study decrease but also helps them for relaxing and improving their study's effect. Secondly, the students need many social relationships. They are the people who will step into 'the university of life" in near future, so they need contact with many mature people so that they aren't embarrassed when they will live and work under the pressures of city life. These people can be their parents, their relatives, the and the people who had the successful careers. Their worldly-wise knowledges and experiences are necessary for the university students. Finally, the students need to join the surrounding environment to get the soft skills such as communication skill, language skill, management skill... These skills help them for practising to become honest, creative, independent, enthusiastic and dynamic... When they graduate, with the remarkable skills and activities, they will attract a lot of employers easily. Besides, many full time university students start a part-time job when they are studying. The employers appraise the experienced students well. The capacity of looking for a good job of the dynamic students is higher than the others. Obviously, it is necessary for speding most of the time studying, especially if the student's goal is getting a good or excellent degree. This is necessary condition for achieving the basic knowledge. But the idle theory may inapplicable in practice. The sufficient condition to succeed is doing many helpful activities to supplement the useful knowledge. In according to the 80/20 principle, the full time university students can manage their timetable suitably as: 80% of their timetable is for studying and 20% of its is for doing other activities.
