There are several reasons to go to university, but people usually do it because they want to reach a better position in their lives (personal development, achieve a god job or earn more money). That’s the reason why, in some cases, people choose a degree depending on the working perspectives of the studies, even when they don’t like studying it.
Can a person be happy doing something he/she dislikes the whole life? I don’t think so. In my opinion, people who have decided to go to university should study what they love without thinking about the money they will earn in the future. Let’s be honest, going to university doesn’t ensure you to get a job, it only gives you the opportunity to have abilities in a subject and be more qualified to perform a job.
Besides, the labor market changes very fast and what today is demanded, tomorrow might not be. Moreover, there are professions that you can’t be tought at university.
Is it necessary to go to university to succeed in life? There are a lot of examples that show it isn’t a requirement. Steve Jobs (Apple), Bill Gates (Microsoft), Mark Zuckerberg (Facebook), James Cameron (film maker)… have succeeded in their professional lives without having finished their university studies. However, even when there are people who have succeeded from scratch, it continues being a rarity that happens once in a blue moon.
