Big fan of Krita as a painting program. You've gotta learn some different hotkeys and all that, but it's better laid out and easier to learn than like, GIMP or Blender ime. Lots of good tutorials, plenty of free brushes, quite customizable. I really like its alpha-locking and groups as an alternative system to clipping masks.
Filing taxes in the US is a cruel and byzantine process. It's fucked that the government has the resources and really the infrastructure to know what people owe, and will go through with finding out from time to time to determine if people are cheating, but all but requires them to use a private service to figure out what they owe first.
