Input: [header] How to be responsible [title] Clean up after yourself without being asked. [step] When you make a mess, clean it up; don't just leave it there for someone else to find. You made the mess, so you should be the one to clean it. <sep> (A) Nothing messes up a perfect home as much as looking after it. If a mess happens, treat the mess like a clean slate. (B) If you are responsible for all the other people's messes, you will be the one in charge. [title] Make a schedule and stick to it. (C) You don't want to be the one to discard your clothes? So think again. When you are finished with your chores, do something else: clean up after yourself. (D) Think about how another person would feel if they came into the mess or if someone had already cleaned it. [substeps] For instance, if you create a huge mess while making a sandwich, take the time to put the ingredients away, wipe up spilled crumbs, and wash any dishes you made or put them in the dishwasher.
