Marriage ;)

Mohabbat mein agar iqraar hoti hai to shadi hoti hai.
Mohabbat mein agar inkaar hoti hai to barbadi hoti hai.
Hoti jo bhi hai,
Mohabbat karne ki sazah zaroor hoti hai !!! 

Simple Choice

At all cross walks in life, the choice is always between "I want to be happy" and "I do not want to be happy".

To make this obvious decision, it takes true character and great strength.

coupling and cohesion

Loose coupling and high cohesion between components
create good systems.
Loose coupling and high cohesion between humans
create great relationships.

The law of conservation

Goodness can neither be created nor destroyed.
Be good, it will come back in a way or other.

selfish

All are selfish.  

Incrementally selfish starting form the farthest metaphoric thing known, to self.

I, my, my family, my friends, my town, my state, my country, my continent, my world, my universe.

And the expression of selfishness is contextual.
