Terms like "fatherly advice" and "father knows best" are common for a reason. Dads give pretty sound advice (regardless of how off-color, unwanted or blunt it seems at the time).
During childhood, their wisdom may have helped us see a situation in a new way ("The smart kids may not be the cool ones now, but they're the ones everyone will want to be in 20 years."), and as we got older, it may have confirmed things we already knew deep down ("I didn't want to have to tell you this, but that guy you're dating is a jerk.").
