You always think that 70 is the end of the road: 'Somebody died when they were 73 good life'. You're closer to death and you better make sure you don't waste too much of your time doing things you don't want to do. No point in saying things you don't believe in.
I always had two or three jobs at the same time. I started doing yard work when I was 7 or 8. When I was 13 I got my first state job doing road construction. Between working sports and school I hardly ever had free time.
