A useful exercise one can partake in at any time is to ponder how they would feel about their sudden death.  I remember running along the canal in Thailand and thinking that I could accept death at that very moment, as I was doing exactly what I wanted to do.  But as I sit here tonight, studying verbal and quantitative reasoning that will be useless to me seven days from now, I feel that my death would be a tragedy, as the manner in which I am spending my time could not possibly be more opposite to those morning runs in Salaya.
