Cannot agree more. I got a cancer diagnosis on the day I got my last medical in March. Not a fun situation. Beat the cancer and playing the paperwork game now, but what you posted is spot on. You never know what tomorrow will give you and if you don't live each day as it's last, you won't know what you lived. Some may say "whatever, not happening to me", but if/when it does, everything you longed for and enjoyed comes before your eyes. For me the worst case was losing my wife, but for #2, it was the fear of never flying again, never running a checklist, or landing after a day most would want a beer to cure. Sounds stupid, and I hope no one has to experience it, but it exists and far too many pilots will have to deal with it. Be humbled with what you get to do, with the understanding of one mistake or fateful doctor visit, it can all vanish.
