What we study is really worthful and can we implement in our future?

You're right. Most of our education and studies are nearly worthless. Besides, specializing in one specific area of study limits you by restricting your knowledge. I feel that instead of specializing in one area, people should learn more about everything. There's no need for scientists when many of their main theories are unproven and unsound. People should be able to branch out to expand their fields of knowledge.

that study gives you overall idea, it is not waste, if you are smart enough you can implement those in your daily life, think again, what you studied, is it not helping you in your life ?

That depends on how you approach what you study, and what topics you choose to study. If you approach your study as just a diploma, or as a way to earn lucratively, then of course you'll think it's worth little in the end. If, on the other hand, you approach learning as a means to an end, as a thing to appreciate in and of itself, then it's worth something. It pays to be informed about society and its ills, it pays to understand how the world works. And I don't mean necessarily in the form of money--it could help your ability to make educated choices in elections or in supporting certain causes.

Education is wide platform to build a base knowledge for everybody and place to pass your time untill to make as mature as you can handle on your own. And in later stage, it split into branches based on the specilisation requirements and provides various opportunities to go forward. Which is called as degree !!! And again degree is a narrow platform which teaches you the depth knowledge in subjects and that helps to start the career. But on the job learining teaches you the corners and corners to become expertise.

well actually we choose a field depending upon the level it stands on the technical field!! most people do that!! they dont choose the field based on their interest!!! and more over... the fact is what you have said is right!! we do choose jobs to get employed in that particular company!!! some times.. we happen to do jobs that are not even related to what we have studied!!!

Yeah man u can if you want and keep your ideas open and work hard towards your goals. Every study whihc an individual makes is and can be used at some or the other point of life. It's actaully similar to the experience one gains while working and similarly we gain experience of different kinds while studying different things. Knowledge of anything is never a wastage. Be positive.
