"The youthful and perennially optimistic grandfather considers himself lucky."
Good to hear the dude is positive and still happy.
We are all lucky to even exist, life is great IMO, just waking up this morning taking a breath of fresh air, walking my dog, and looking at the sun rise over the beautiful fall colors makes life worth it. I then bent over to pick up the poop that my dog left on the grass. Did I complain that I had to pick up poop this morning? Poor me, having to pick up poop even though I'm a trader and should never have to do such a thing!! We all put our underwear on the same way. Just humans. No one should have self pity IMO.
The guy is probably thankful he is still healthy enough to even work.
Everyone's worked "shitty" jobs at one point or another. It's how you perceive it.
The world owes you nothing!
