See, here I am, still thinking "I'm grown-up" because I pay bills, take care of a house, go to grad school, relate to other grown-ups... But I'm pretty sure that in another 10, 20 years, I'll look back at 30 and say "Man, I was still pretty dumb."
When I was 18, I didn't THINK i knew everything. I really DID know everything. Since then, I have forgotten a great deal of everything.
And I don't care if that makes me "ageist" either. It happens to be the truth. I'm just telling it like it is.
So my advice to all the 18 year-olds is to either stay 18 forever, or write down every thought you have so you can refer to it when you're over 40.
