I tell you what I love - and I think you get better as you get older - when you're younger and you don't know what you don't know, you tend to talk more about what you think you know. You shut out the opportunity to learn what you don't know.
There was some expiration point to my life, and it became very important to maximize the time that I did have on Earth. That's what led me to my personal philosophy: "No Opportunity Wasted" - NOW for short, which is about living life to the fullest.
