yea charms and lucky items can be a good moral booster.It can give you the extra boost of fuel you need.

off the top of my head i think i have: the ultimate survival guide by john lofty wiseman, a small inflatable pillow that folds easy(which has multiple uses if you think about ,that i have discovered).
some little packs of sweettarts.all of the above in my bob.
and i always try to carry a cross on me when i can , that and prayer really do wonders for moral.
