Who do you think are the Luckiest People?

Barbara Streisand used to sing a song in which she says, the luckiest people in the world are "People who need people."  Maybe it was appropo for the album or movie but it was words in a song.

The luckiest people in the world to me are those who have good health, boundaries, self respect, good work ethic, kind intentions to all and actually "KNOW" what they want to do with their life. How much are these are born or developed?

What do you think the luckiest people have as characteristics and how are these obtained?
