Mary Balogh said this quote

Sometimes, one yearns for something.For the ultimate in happiness. I yearn for it,and don't know where to look for it any longer. And I don't know if I would recognize it if I found it. And the longer I look, the more selfish I grow.For I think only of my own happiness. i think I have lost the ability to make someone else happy. If I ever had it. And I suppose we can never be happy unless we can also give happiness.
