We should focus in our life not in others because it will ultimately save our precious time which we can use in thinking about our own ambitions and in this way we will also be liked by many people if we don't interface in others matter.
Focusing in our own life makes us strong and confident as we have the time to think about our problems and their solutions rather than others so we know what is good and what is bad for me.
Of course academics will be your main focus . But there’s more to student life than going to class and attending lectures. It can be like being a wonderful human being. Then can achieve whatever u want. Automatically everything comes on your way. But to become a good human theres only one way.

Relationship with God is the only thing that will quench our soul's longing. Our greatest desire is to know God, to have a relationship with God. Why? Because that's how we've been designed.
