Bristoe: I disagree - I have lived a long time (72+ years!) and there is NO "line" of things following me that I wish I'd done differently.
Making good, sound, conscientious decisions all one's adult life is NOT hard to do.
If I can do it, anyone can who has a mind to, can do it.
Some people just carry a mentality where they ignore the fact that "bad decisions" (immature, self destructive, criminal etc etc etc) won't create troubles for them - and they go on to "make mistakes" that can, and often will, haunt and or cause troubles for them.
