The answer is given in Philippians 3:7-8:

Whatever gain I had, I counted as loss for the sake of Christ. 8 Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ.”

In other words, Paul displays the worth of Christ by counting everything else as loss for Christ’s sake. “I count everything as loss because of the surpassing worth of Christ.” Which means that the life that displays the worth of Christ—the unwasted life—is the life that uses everything to show that Christ is more valuable that it is. Money is used to show that Christ is more valuable than money. Food is used to show that Christ is more valuable than food is. Houses and lands and cars and computers are used to show that Christ is more valuable than they are. Family and friends and your own life are a place to show that Christ is more valuable than any of them.
