It becomes a burden since we become dependent on schooling to define our future and overall image of our life. Society becomes obsessed with the idea of 'education = jobs = future'. The plan for our life had been set up since the day we born, to follow what society expects us to do. The idea of 'learning is to enjoy' gradually turns into 'learning is to survive'.
People start to view education is just a tool to help them get a job, not something to enjoys during the process. Most of them learn for their job, not for their desire for knowledge. And education is losing its value of knowledge since people start to use it as a short-term benefit. Once they get what they want, they will abandon it like it has never existed in their life.
