Inspiration stones are crystals/stones that have been polished and have a word carved into one side.  They are great to carry in your pocket or place on your desk and you can rub your thumb across the word, or periodically glance at it to help with worry, stress, or motivation.
 
Listing is for 1 inspiration stone.  I will intuitively choose the type unless you put a comment in when ordering requesting a specific type of stone or a particular word.
