What is the achievement of life?

"Some people live for the fortune
Some people live just for the fame
Some people live for the power, yeah
Some people live just to play the game"
It's a verse of a song named called "If I ain't got you" by Alicia Keys, my favourite song. Each time I listen to this song, I (always) think about the things I have to do in my life?
And I asked myself: "What am I going to do in the future?"
Get a dream job? Get married? Get rich?
I believe that every person has their a fate. I'm still finding my own one. <em>or</em>  'I'm still finding mine'
