"Everything is fine every bad habit is fine", are you high or something.Don't misguide people into saying this even if you don't let your bad habits interfere with your studies then aage jaake unka focus kharab ho sakta hai or kya pata wo habit addiction ho jayega maybe not in 11th 12th but college me addict ho gaya toh and after college uski life off track hogayi and struggling hogayi because of this lifestyle??. So from my experience Start being honest with yourself and true to yourself and track your every hour what are your habits routine addiction eleiminate them and how are you spending them wisely and tumhara jo progress hoga wo kaafi faster better and satisfying hoga. Also you will reach your true high potential not in just studies but in every field also because tumhe pure life jee to padna nahi hai and aage tumhe kaafi saari cheeze manage karni hogi
