In 2005 Steve Jobs gave a speech at a college commencement. I was reading this speech and one paragraph really stuck with me, and I thought you might enjoy it as much as I did:
"When I was 17, I read a quote that went something like: 'If you live each day as if it was your last, someday you'll most certainly be right.' It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: 'If today were the last day of my life, would I want to do what I am about to do today?' And whenever the answer has been 'No' for too many days in a row, I know I need to change something."
Hope this will impact you as much as it does to me.
