Oh look a bucket list!
Items, photos and other stuff that I will obtain during my bucket list ventures will be stored within a jar, so when i’m old and decrepit I can look at everything within the jar and regale/bore people about the quests I went on! And everyone is invited!
(Things will be added to the list at any point.)

Great List! I like your idea of keeping the things in a jar. I’ve been writing a little about each goal I accomplish in my list (I have 2 list items/page in a journal, with space between them to write) but I was wondering about whether I should/how to keep the other things like ticket stubs etc.
I think that keeping something of the experience is always a good idea as then you have something tangible to hold on to, the item doesn’t have to be huge at the minute my jar holds mostly tickets or receipts and photos(as well as a shoe lace). As for what to keep them in I think that a little wooden box or a mason jar is always a cute and cool idea as you can personalize them and they are cheap!
