If he had studied and got into a normal highschool instead of a delinquent school things would be different.
If he had not pissed off the school banchou things would’ve been different.
Had he not become a shut in things would’ve been different.
Had he not lost his last friend( which he remembers during Paul reunion arc) things would’ve been different.
Had he attended his family funeral(the siblings might’ve given him part of the inheritance instead of catching him red handed fapping to loli porn) things wouldn’t have ended up with him having no fortune and ending up homeless.

What MT simply showed was that if you miss so many opportunities to fix your life you’re gonna get checkmated one day.

If you manage to get that second chance don’t waste it.
Care for your family
Care for your children.
Raise your children and set them on the right path to ensure their success. Marry them off to influential people if need be for the sake of your House.
Connections>Nakama power
Not everyone you meet you have to make into a nakama but connections are important they’re directly connected to getting you wealth and into an influential position being alone no matter how powerful doesn’t work in human society as no matter how powerful Oldeus got he would get stomped. And he did eventually fail.

Connections>cultivation

And a bunch of other things but MT at the end of the day is simply an entertaining story as it’s meant to be without author trying to preach anything.
