The meaning of life?

'Death is imminent for everyone..

When u are about to die, you want to leave something behind for those around you.

Even if you pass away, you want those you leave behind to live happily.

I'm able to do my best to live because i thought this way.'

** came across this dialogue when i was watching a drama **

Life is short.. I really cannot understand why people insist to be calculative with each other, petty with each other, picking on each other. It especially sad when we are working in a cancer setting, dealing with patients who faces death angels everyday, for what????? clueless.. =(
