I think that this kind of advice can be detrimental to people like me. It basically says force yourself to study 5 hours a day no exceptions. If you get a job or other extracurricular activities don't count it as work time. Well, I lived that lifestyle in high school. I studied 4 hours a day, limited every extracurricular activities to not interfer with my study time. At the end I believe I have missed a great portio…
I am a victim of this, Because of the competitive nature of things in my part of the world, I had to skip the extra curricular activities and dedicate all my free time (4-5 hrs a day) for studies and I am completely out of balance now. It's very difficult for me to find a balance or enjoy the activities now.
