1 Page at a Time: A Daily Creative Companion, published by f***ing Penguin Random House!!!! This item is not available from me directly but other than that it is very, very, very me. If you like other stuff I've made, this book is basically stuffed full of that.
It pushes you through 365 pages worth of introspection, motivation, and ridiculousness to help you make the most of a full year, no matter when you start it. It's part journal, part creative inspiration, part "kicking you in the ass a little but nicely I guess????" It's great and weird and friendly enough but not necessarily "for kids" either.
Available in over a dozen languages worldwide (some of these editions are also available with the link above).
