just my 2c but its good to have debt such as mortgage debt allows you to build more wealth and compound wealth earlier & faster. Most low interest non callable debt are pretty good. As far as car wise I agree with him.
when I started investing when I was 17 in jc this was kind of my goal as well, working, saving, investing sort of became my hobby/life . When I was around 20 late last year I had accumulated about 100k but at the same time I still felt empty, Honestly the depression started setting in and I started asking myself if this goal really made me happy. I realized there are other goals more important to me than gaining wealth and retiring early (I thought retiring in 30s and playing video games/watching anime would make me happy). But I realized I didn't care about that and there were other things that would make me happy like being myself, finding a partner and settling down. It would be nice to retire early but for me its no longer a priority in my life. I find myself focusing on improving myself starting late last year. Basic things like hygiene, skincare, eating healthier, exercise and mental health.
