Is School like a Prison?

I'm in school to b educated and of corse to fulfill my goal in life. I believe that each of us has a purpose that God has set us to do bt we just need to seek it. If I'll be living in a worldwherein I don't know my purpose; well life will be worthless then. With relation to school, to be specific I want to be an engineer someday and I can only attain that dream if I study. Studying may be hard but that's life. We all will deal with a lot of trials and with those hardships help us to be the better person who we want us to be. Studying may be a trial but will be a good tool to be a success.
