i have always been nomadic at heart, so my favorite thing to do is just pack up the car with camping gear and snacks and pick a direction. make sure you have gas money and stop at all the stupid lil stops you see along the way like the world's largest rocking chair and only eat at small local restaurants and drink too much caffeine and take lots of pictures. it's so freeing and you'll have so many fun stories.
e.g. don't buy a $100 dress that mostly sits in the closet, buy a $100 boar-bristle hairbrush instead that you will use for life and will make you feel fancy every day.
