Yuuki

I am mustering up a lot of courage or Yuuki these days! I have a book coming out later this month and that means I will be doing a lot of self promotion. 

So here's to Yuuki!

the Japanese word for courage is: 勇気 (yuuki)

The first character has the meaning 'brave' and the second is 'spirit'. I should think leaving off the second character would be fine unless you were using it in an actual Japanese sentence (in which case you'd likely be representing the word yuuki and so would need both)...

...according to Jim Breen's WWWJDIC 勇 (yuu) can stand alone as a noun, meaning "bravery; courage; heroism"...

I started a new FB fan page for my book so if you haven't yet—please go and "like" it!
