Idk why some people (knetz especially) think that being a kpop idol is such an easy journey and not as hard as studying in university and every successful celebrity is just "lucky". Dancing and singing is never easy in my opinion. Imagine have to memorize all the choreo, have to train your vocal everyday, need to have a really strict diet, not having any freedom like others and also constantly living in a world that is not guarantee (if you still a trainee). And once you debut, its not the end as you still have to work harder to established your name and to compete with others in such a very saturated industry. And suddenly once you reach the top people will say "What an easy life they have". 
Also its not like idol didn't study at all some of them even graduated from college and university. I also will never understand the narrative that being a celebrity is easier for you to be successful in life. As if there's only around 5% to 10% that really made it out of ALL group that debuted throughout the years.
I will never be able to keep up with all the task that trainee need to do and personally i find that studying is much more easier than have to memorize choreo and working almost 24/7 without any rest.
