Nearly every one of my closest coworkers are way better of than me. Like, a lot. Hot cars, nice homes, investment properties, personal airplanes, million dollar retirement funds, lasting marriages, successful children... it's hard not to feel a little envy, but I have never held any of that against them. I am inspired by them. At 43, I am the youngest guy in our engineering depth, and most of these guys will be retiring soon. I'll miss them.
