I hope the title brought you in because otherwise I don't know how I would get you to read about taxes.
Keeping it short--on Day 195 of my New Things project, I did my taxes. Now that I'm a grown up, I have to do these all by myself. Only, I actually recruited my accountant friend Tasha to help me do them on Turbo Tax...and even then she had to actually take them back to her office to finish them. So I didn't realllly do my taxes, if you want to be literal. I did, however, attempt to do most of them, and that's pretty grown up in and of itself.
