My daughter just finished college while working full-time too. So it's not just for my generation. Even though my wife and I budgeted for years and saved up to put her and her siblings through college, my daughter was big about maintaining a work ethic and investing for her future. I challenge you to find a father more proud of his kids than I am.
You are justly proud. My daughter took the toughest academic route possible (IB) in high school that earned her a full ride scholarship at a state university. She graduated Summa cum Laude and finally dipped into the money I had saved for her to get her Masters. They can make "your cup runneth over".
