Peace Of Mind lyrics

I've had everything that money can buy,
Oh, but still I'm so unhappy darling, that I could cry
Because I've never had peace of mind, darling, in my life time

When you're in trouble and all down and out,
Then you'll find out, darling, what it's all about
Then you'll realize that peace of mind, darling, is hard to find
[ Lyrics from: http://www.lyricsmode.com/lyrics/b/bb_king/peace_of_mind.html ]
I've been everywhere, seen everything but I only have myself to blame,
For not realizing while I was riding high that happiness is something money can't buy
Oh, the things I haven't done, darling, are very few
Yes, I've had trouble baby, and good luck too
Oh, but I've never had peace of mind, darling, in my life time
