Not long ago I spoke with an old high school friend who was dying of cancer. I hadn't seen him in many years, and we were catching up. He told me, "I worked this job for a while, then I did this, then I did this job" and he added, "That was a wasted decade."
I don't know if you have a full decade in your life that you feel like you squandered. Some people feel like they've wasted their who life. How can you make sure, when you get to your death bed and someone asks you about your life, you'll be able to say, "Well, I certainly didn't waste it"?
