I ask my parents for advice all the time and I'm 44. The big thing is, for the last 10-15 years, they ask for my advice more than I ask for theirs. I can assure you, at 22 years old, I was taking all the advice they'd give me. At 30/35, I was taking a lot of it. I am fortunate to have them around to give it at 44 and hopefully they'll still be here when I'm 52.
Kids should get guidance from their parents. The problem is some of these kids' parents are idiots. Unfortunately, it can be hard for the kids to see that until they are much older.
