When I was 32/33 I was in the best shape of my life. 6' ~180 lbs and lots of muscle. I was running 5-10 miles a day every day.
But everything else was still the same. I felt the same on the inside, nobody treated or noticed me any differently on the outside. Women still were not interested in me. My job didn't pay me more.
Eventually after a few years of maintaining that, I figured why was I bothering? I got nothing for the effort of being in good physical shape beyond being in good physical shape. In fact, I was sometimes more depressed because at least when I'm out of shape I can say maybe if I were in shape somebody might like me... but in shape and still nothing? Why bother.
