They know a lot, but they don’t know everything, and they can’t advise you on anything.They can only tell you what they believe worked / or didn’t work for them.

"An approach, according to which children should fulfil their parents’ dreams/ do everything in order to make their parents happy/ provide their parents with a peace of mind, or whatever they want for themselves - because they owe it to them for all those years in which their parents took care of them - is utterly selfish."
