Here’s what I love about being an adult: you can do things. Not that you have to do things, but that you have the power to do them if you really want to.
If you don’t like your job or your field, you can change it. If you want to ditch everyone and check into a hotel for a week, you can. If you want to move to a new city, you can. If you want to get a puppy, you can. If you want to get a makeover, you can. If you want to go see Athens, you can.
You may not choose to actually do any of the things. You may have other considerations or other places to put your resources. But it’s your choice, because it’s your life.
Someone I know who got married a fair bit older than I am told me that happy though she was, she was afraid of losing the independence she’d grown so accustomed to. For a year, she kept her passport in her handbag. She knew she could always flag a cab to JFK Airport and hop on a plane to Paris if the mood struck. She never did it and never even contemplated doing it. Knowing she could was enough.
