Don't make the mistake of thinking that your useful life is effectively over at 42. At 42 I was starting over: new wife, new child, new job. I had neither the proverbial pot nor window.
Today at nearly 72 life is pretty good---nice place, lots of toys, no debt and pretty good chunk of cash in the bank. No question that luck played an important part in that, but you have to remember the old adage, "The harder I work the luckier I get." I did work: work was my hobby---my only hobby. I don't fish, hunt or golf. I looked at the work as something fun; I liked a sense of accomplishing things, making something out of nothing, making something better. My point is, I suppose, that most of us have to work, so might as well enjoy it. You're still young, whether you think so or not. You've got plenty of time.
