Keeping a journal is pretty fun.
The best thing about it is you can do it any way you like. With a pen or a keyboard, add pictures or stickers or tags from your tea bags, write every day or just when you feel like it, and if you don't want to see something you wrote ever again you can just tear out the page(s) or delete it. It's just for you, you can do it entirely your own way.
