Respect your elders. Don't expect anyone else to support you. Maybe you have a trust fund, maybe you'll have a wealthy spouse, but you never know when either one might run out . Don't mess too much with your hair or by the time you're 40, it will look 85. Be careful whose advice you buy, but be patient with those who supply it .
Advice is a form of nostalgia.
Dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it's worth. But trust me on the sunscreen. This is not one of those updates. As I was driving in to work today, I saw a tiny blonde woman driving a Ford Expedition . She was obviously recently married, expecting to have kids within a few years, and probably lives in a single family home in the suburbs.
