dont be a bitch about it
acne:
wash face daily
replace your pillowcase every night with a new one, or wrap a fresh towel around your pillow every night
distance running (oh god the horror!)
work out:
just do it, try taking a martial art, it's loving awesome. i'd recommend krav maga but the classes are rare
get a gym buddy so you two can bug each other to go
also don't be super nice all the time, then you look like a bitch. girls are animals, they respond to the alpha male.
