Isn’t that a great question? I got it from an old Gretchen Rubin podcast episode (at 10:35) and I’ve been pondering it. I love symbolism, metaphors, coats of arms, magic objects, charm bracelets, sandplay therapy etc. so this is right up my alley.
Some of mine are:
tree
notebook
train
castle
clock
What are yours?
Have a good Shabbos!
