Those who wear makeup to uni, how???

I see a lot of girls at my university who put in effort into outfits and apply makeup, styling their hair etc. Some wear a full face of makeup, others just a bit of mascara, blush and gloss etc. They look pretty and good for them, I'm not judging them sorry if my title seems that way. But my main question is... how do yall have the time and energy?!! HOW?! Please share some of that energy with the rest of us, I'm begging you. As a full time student it takes a lot of energy to attend all lectures and seminars in a week, plus study and get a good night's sleep. So it baffles me when I see girls at 9AM LECTURES in a full face of makeup with styled hair, it just makes me think "I truly could never but good for you". Those who wear makeup to uni or put effort into outfits, how do you have the time and energy?? Especially with an intense schedule and several 9ams. How much earlier do you have to wake up to do that? Like 2 hours, 1 hour, 30 minutes etc..

I'm in no way saying these people shouldn't, I understand freedom of expression, and love makeup myself. Perhaps it's just the jaded 3rd year in me but jeans and a jacket is all I can be bothered to do. Always fun to see others outfits and creativity though :D
