Ya, if you don't acknowledge the luck involved in things like getting that good job, it can offen imply everyone else is just lazy and it's hard to be congratulatory when most people just don't have the circumstances work out for them.

It could come down to your first job working out super well, paying well, and maybe you also happen to not find it extremely depressing. It helps if you're parents are still together and didn't have their own mental health issues, or less likely it helps of your family is so screwed that you had no other option than sacrificing yourself fully for money. That carries you forward. If however anything happened to impair that, you could be screwed.
