- Ratio between thinking and doing. People call it overthinking, I don't, because in some cases, I prevented myself some nasty situations (e.g. any form of addiction, scams and similar things). So it has been beneficial as well, but I think it took more than it gave me back. - Less relationships and more dating. Though, it might be the case that I'd want it the other way around since I did this once in my life and got tired about it after 5 weeks (traveling, having intimacy -- kissing and/or sex -- with one woman per week). I think this points serves to show that even if I could redo life, it doesn't mean it'd be better at all points. - Not study as much and get a job ASAP. I started a first serious freelance job around 27 (being a TA before). In retrospect, I should've ditched my extracurricular study stuff and started making money at 22 and invest 50% of it. Preferably, I'd have gotten a job at 16 (20 hours per week) and started investing 50% of that. I don't regret investing late, despite the fact that I don't have the amazing compound interest of a 16 year old. But I do regret not having any focus on building up some capital. Especially because I don't have access to high paying jobs, despite being a programmer and despite delivering good work (I am terrible at job interviews as I'm simply myself and find it hard to apply to one role). I have some now and have needed to rely on it at times and it saved me a ton of stress and related mental health issues (potentially caused by stress [1]). [1] I know because there has been one time where I did get hit by stress for a bit too long (6 months). If it would go unchecked for a couple of years, then a moderate depression might be what you're looking at.
