Are you living your life like it is a dress rehearsal?

Months ago my neighbour was doing renovations to his house and as we talked to him about the huge scale of the renovations he was making, he said “I am doing all this now because I am 70 something and this is not a dress rehearsal!”  His statement caused me to pause and ponder… Am I living my life like it is a dress rehearsal? Am I complacent in my life and seeing it as a practice run before the main event?
