Stop asking yourself whether you like or hate a person. And start thinking if the person is your favorite or a non-favorite. That's how you kill hatred.
The Joy you get from achieving a goal will always be temporary. The moment you reach it, you start thinking 'what next?'. True happiness lies in the journey.
We are in a world where negativity has become so predominant. Why is that these days it takes less than a sight to hate & judge someone and takes Eons to actually like them?
