I started doing this in 2013, although I quickly gave upon the idea of a jar (or decorative tin, in my case) and bought a pretty notebook instead: it had occurred to me that I might want to keep the blessings/memories I’d written down, and couldn’t see a good way to do that with scraps of paper.
I didn’t think I’d manage to fill one book in the year, but before too long I found I was writing in it most days (it’s a very bad day indeed if I can’t find anything to write at all) and now I’m on book 4. The books I write in have memento pockets at the back, and the current book, although only started in October this year, is rather full! I keep train tickets, cards, notes that people have sent me, info leaflets from the churches or cathedrals I’ve visited – all sorts of things.
Count your blessings as you go, and more will come your way ❤
