Contrast paragraph: decision of study or not

Nowadays is very common to make the decision of study or not. Long time ago it wasn't necessary as nobody used to study, they just worked since they were child. However, today everyone have the chance of study at high school or at college but some people dislikes this option. Both have pros and cons. On the one hand, people who studies might spend much time that they'd like studying and not doing the things that they really want for instance. Sometimes the fact that you're friends are spending a good time while you are studying is frustrating.Though, every sacrifice is rewarded. It means that in the future they'll have a great job and a great life, in most cases. Whereas, people who had decide not to study maybe have a great youth. They can going out whenever they want, sleep lots of hours or spent all night watching TV. Also much people instead of study in their youth they work in bad conditions in most cases. I think that if you work hard in studies when you are young, you'll have a good live. As I said before, every sacrified is rewarded: we won't have what we want if we don't work hard.
