> Forget becoming manager at McDonald's or be even good at flipping burgers at the age of 40: you are competing with 20yr olds doing sports with amazing coordination etc

I have no idea what in the world you are talking about. Most 20 year olds working at McDonald’s are stoned and move at half a mile an hour whether it’s a lunch rush or it’s 2am. I worked retail for years before I finally switched full time to programming. It’s certainly not full of amazing motivated athletes with excellent coordination. You’re lucky if most of them can show up to work on time more than half the time.

Do you really wanna be competing with those people though? I'll be honest, I don't even want to be in the same room as them.
