If you're young and sharp, programming looks like paradise. It's more or less a meritocracy, there's a ton of personal freedom, and you get to spend your days doing creative, challenging work and getting paid fairly well. You may not have even had to slog through 4-5 years of college.

You'll start to see the downsides as you approach 40 though. Many programmers can't play the social games that management requires, there's a limited number of "architecture" slots, and you're suddenly competing neck & neck with people twenty years younger willing to work 60+ hours a week for half your salary. It's brutal but you've just got to knuckle down and do your best to keep up. Leverage your experience to learn new tech faster and constantly work on moving yourself upmarket technically. You've been in a footrace all this time but you may not have noticed it until now.
