Pick up after yourself.
If you live with a roommate, whether it is your wife, girlfriend, or even some random dude, share the chores. Remember the whole point of this book is how to not be dick. Pitching in around the house rather than being an entitled fuck head is a crucial part of this equation.
Wash your dishes. Wash her dishes. Wipe the toilet seat and put it down after you pee. Make the bed. Put your dirty laundry in the hamper. Wash, fold, and put away your laundry.
Generally act like an adult and take care of your most basic simple hygiene needs. It isn’t cute to live like a slob, and it is even less cute to be stuck in some outmoded misogynistic rut of expecting your chick to do all the house work. This is the modern world, get with the times and take responsibility for not being a pig.
I have been paying someone to clean my house since my early 20s. I was working menial construction jobs and paying a housekeeper my same rate because I prefer to carry beams than scrub toilets. If you prefer not to wash dishes, swab commodes, do laundry, take out the trash, and so on, than pay someone to do it for you. I guarantee your lady will not be upset by you hiring a maid to keep your house nicer. If you don’t have a lady and your house is a dump, well you know what they say, “dress for the job you want” aka “build it and they will come.”
If you think you don’t have the cash or the time, well you better start figuring out a way to make more of both… Right now.
