Yep. It's called 러셀의 인생론, but I think it went out of print (mine was originally my mom's book published in 1986). This book is a collection of some essays of Russel's. Instead, there's a new translated version(with a different title) of this book available and you can find it by its english title - the conquest of happiness.
I guess you're having a great time there, huh?
My parents told me that I went to Japan Disneyland when I was three, but I can't remember it at all. :D
btw, are you gonna travel somewhere else in the U.S. after the session?
