Nothing makes you feel like an adult more than making your bed. There are all sorts of blog posts and articles on why this habit is good for you (all of which I ignored for years), and I’ll let those speak for themselves. Coming home to a nicely made-up bed is one of the best feelings in the world! Take the extra 45 seconds to do that in the morning.
Whenever the DMV/dealer/repair shop/oil change place gives you any paperwork related to our car, hang on to it. Get a folder or a binder specifically for this purpose and keep all those pieces of paper organized in chronological order. If you ever want to trade in your car, this is how you’re going to be able to get a good trade in value- keep all proof that you’ve put time and money into keeping your car in good shape.
You probably already know this, but I think it bears repeating: EMPTY THE LINT TRAP IN YOUR DRYER! Not once a week. Not when you remember. Every. Single. Time. It’s the easiest thing in the world to do, and your clothes will dry so much faster. Not to mention you’re less likely to have a dryer fire break out. Do not press start without cleaning the lint trap!
(OK I’m done.)
