Possibly a bit off topic, but I read this submission last night (and gave it the first upvote) because today is my 50th birthday. I am a software engineer that has followed a somewhat unconventional path, but have enjoyed my career passionately. I have told myself that turning 50 is no big deal because it's just another arbitrary day, and 99+% odds I'm well past half dead already. But, because others around me keeping making a big deal out of it, it's hard to not get caught up in some transcendental introspection. If you're well past 50 (approaching 60 or beyond), what would you tell your 50 year old self and peers?
