After being in as a fan of BTS , as an army and as a fandom of  other kpop group, artist and soon , i know how much it is important to love yourself in the first place . 
Always love yourself.
Before meeting BTS  for me love is love not selflove I only think that being happy is enough but reaching in teenage happiness is not enough . A teenager need selflove , happiness, control ourself and always be in a positive mind . but not only teenager but everyone in this beautiful universe.
Still if you want or you will become then family even own parents , relatives and society will say "you are to much selfish , attitude ,greedy and egoistic " which you not in reality . Being a introvert or obedient are highly dangerous which cannot be said to anyone. yet I am a shameless being i tell my problem to my friends and mentors. Atleast I once I want to enjoy few things at the present time rather than waiting for myself to become successful in life tho still i will never be enough.
