What is really important in life?

I just finished looking at pictures from someones "pre-wedding" times and a few from the big day.  Only for this young lady, she's suffering from a rare cancer and had to shave her head 3 weeks before her big day.  Her "honeymoon" the monday after her wedding began with a round of chemo therapy. Every picture brought more tears to my eyes.  I don't even know this young lady, probably will never meet her. It just put my life, my purpose and the time that I spend with my husband into perspective.  I know it's relatively cliche and I say it all the time, but it's true.  I'm lucky to be healthy...why do I waste so much time worrying about the unnecessary and doing things, that aren't "paid forward."  When will I truly realize what is important in my life...my only "need" right now is a pair of blue jeans that make me feel great...and then I don't really "need" that either.  Guess I'm doing pretty well aren't I?
