I am also sympathetic to the stories above. I have TOO many to tell and the thought of some of the people who have let me down just raises my blood pressure. And my Sawbones says that's bad for an oldtimer like me.
BUT, my two kids (28 and 26 yrs old), accomplished by any measure AND of whom I am quite proud, are different people than me and their mom in terms of how they value their "free time".
The way me and their mom worked to "make it" -- the hours, the sacrifice, etc --just is NOT part of what makes life worth living for them.
Again, my kids excelled at everything they did...but if that "little extra" to be the very best conflicts with their quality of life as they have defined it, they are not going to do that little extra. Love 'em to death but I don't get it.
Someone called it, and i think its true to a degree, "Millennial Generation" behavior ..people born in the 1980s to about 2000.

Anyway, "young" people by definition have room to grow and develop better habits and skills, so I still try to help even the ones who burned me in the past if they come to me again -- after a few years staying on the right path though.
A few others just seem beyond my help...and that saddens me.
