the hard decision which courses to pick

Choose to Take courses in a variety of subject areas or to focus on a single subject area

Since I am still a college student, I would prefer taking courses in a variety of subject area.You know, the reason I choose it is that most us students don't know what we like or what we are interested in, so we need to learn as much as possile until finding the area relly interested in and good at.

Like most people, they do jobs they don't like at all only for money or steady life, but they aren't happy.And I believe choose interest as our career would help us upgrade happiness level, so that's why I prefer taking course in variety area.

Could you please help me improve my script and make it sound more native? Thanks !
