An entire sea of water can't sink a ship unless it gets inside the ship.
Similarly, the negativity of the world can't put you down unless you allow you it to get inside you.
Disrespecting your parents at home and respecting everyone outside is just a shit.
According to me, it doesn't actually matter how successful you're in life if you disrespect your parents from whom you have your identity now.
If you are able to argue also even in that case also, they have made you learn the things by sending you to good school by killing their needs just to give you quality education.
So, think and act accordingly!!
If you want love for short time, love your interest, passion, skills..
If you want love for little more time, love your friends..
If you want love for years, love your family..
But if you want love for life and even after life, love your work.
Because everyone will remember only for your work, nothing else.
Having said, karm karte raho, Fal ki chinta mat kro!!
