Shove everything under your bed.
Put your cell phone away, turn off the computer & tv, no distractions. Get a trash can and throw anything that needs it in there. Pick up your shoes & dirty clothes and put them in the hamper or closet if they are shoes. Make your bed, pick up anything else laying around, dirty dishes to the kitchen, stack books or whatever ^vacuum, wipe dust and it should be good.
Get Three extra large garbage bags. Stuff everything into them and hide it all under your bed. That's what my kids always did....then they'd ask me why they had no clean clothes.
Blow it up. That worked for me, not so well for my parents though.
don't throw **** everywhere and put things away properly when you're finished with them - clean regularly
