I am a coffee person. I tried once to abandon caffeine and discovered that self improvement is not a hobby I support.
I do support humorous, historically themed coffee mugs. Society6 is currently holding a 15% off of everything sale. You do have to click this link to get the sale applied to your purchase. https://society6.com/shawnwritesstuff?promo=FPCFWZ37HRYV
