I took dance for six years. I think the makeup needed for recitals traumatized me because when I was about 10 or so, people would say, "Oh, soon, you'll be wanting to wear makeup..." and I would stop them there and say "Nope." And it's taken me until age 19 to willingly wear makeup on a daily basis.
I flat iron my hair when I'm at home, even if I have no place to go. Mostly because I can flat iron it and keep it that way for 2-3 days, and it's out of my way. Definitely takes me longer to do that, but it's well worth it being out of my way.
Prepare for teenage logic: I don't make my bed on a daily basis because I don't see the sense in it when I'm going to be getting back in it 15 hours later. It gets made when I put new sheets on it or if we're expecting company.
