What does it all mean?

"But what does it all mean?"  said the boy to his grandfather.
"Well, my lad, meaning is subjective to interpretation."
The boy looked blank.
"Well what does THAT all mean, then?" he asked.
The old man smiled sagely; warmly; knowingly at the boy.
"The first thing you must ask yourself is who am I?
Where do I fit into the plan of my life and of those around me 
Whose life plans are affected by my choices. "
The boy chose to look puzzled, which made the old man chuckle.
"People all have there own agendas, desires, needs and feelings 
So you are asking the wrong question, lad. 
It's not 'what does it all mean?' at all, 
But 'What does it all mean to ME?'"
