First off, correct me if I'm wrong, but I think that college and university are somewhat interchangeable. But college is just a bit broader, so I think that instead of writing "colleges or universities," you can just put "colleges."
They think it is necessary to study in colleges or universities is necessary for starting to get a job.
This will make things more succinct.
If they finish schoolgraduate , they will be a professional of their major.
Shorter and sounds better. :]
Some say that people can study alone, but itthat has limitations.
Here, I think you should "it" to "that" because it seems a little ambiguous to me. By using that, it'll be clearer that you are referring to that action of studying alone.
For example, if you try to solve a difficult mathematics question on your own, you might not solve it in even a whole day.
This might add the effect you want. Now it sounds like: even if you are given a lot of time, there are some things you cannot do alone. :]
Colleges or universities provide those kinds of help for every day life, not just for securing a good job.
What kinds of help? Try to be more specific.
Moreover, humans need more than clothes, food, and shelter. Moreover, p eople usually pursue education to earn the esteem of the public and to achieve self-actu alization because we are ideal beings(I'm a bit confused here. What do you mean by "because we are ideal beings?") . Colleges and universities are places where people are satisfiedfulfill the demands of living a good life.
I don't know... to me, the transition to this section seems a little abrupt. Adding a smoother transition to the first sentence should help. Although I understand why that sentence is there, I think it will be better if you leave it out.
Furthermore, in college and universities people learn how to live in society without protectorson their own (? To me, this sounds more sophisticated.. but it's only a minor suggestion :) .
they have to do everything themselves, such as washing their clothes, cleaning their room, taking care of lots of bills, and so on... If they do not keep the rules, they will get penalties, b ecause they are not children and they arebut adults ...Nobody can do it(Nobody can do what for them? Be more specific) for them anymore. That is why they,so have to learn what their responsibilities are. They have to know that making errors and fixing them, is learning, and there are chances before they go to society. Society will not allow their mistakes... People who have more knowledge than the others can get receive more opportunities and benefits.
