what would I lose?

When we get to some point of achievement in life, (or sometimes at a failure) we value ourselves by asking the question " what would I lose? "
Most often people stuff many things in their back pack. 'Back pack' here is the metaphor for the burden of life. Too many things in your back pack weighs you down from doing things that matter. It gets too heavy, by the day.

A good question to ask, time to time, is, " What should I put in my back pack"

Talking about back pack, 'Up in the Air' is a very good movie to watch.
