I would have become Catholic sooner, been a better husband, father and son. I would have had a tutor in math and got a technical degree instead of a business degree, and I would have gotten more serious with my 401K investments earlier on. My father, God love him, and I miss him very much, suggested I become an engineer and me not marry the woman I'm with now, though he said she was the most beautiful girl I ever dated. He ended up loving my wife very much and realized I didn't make too bad of a career choice, either. My main regret now was thinking he'd be around longer than he was, and how woefully unprepared I was at being the head of my family.
