I don’t understand that attitude honestly. Education in any form will only benefit your life, even if you don’t actually end up using your degree in a job it’s still time well spent and it’s still valuable.
Also don’t understand your teachers being so snobby and dismissive of a normal education path???? What a horrible attitude.
Do what you want to do, regardless of what anyone says. You will regret it if other people’s irrelevant opinions stop you from doing what you want but you won’t regret pursuing your goals and getting an education.
