Ralph Waldo Emerson might strike the right chord:
For everything you have missed, you have gained something else, and for everything you gain, you lose something else.
That's very popular thought which I seen many times from different authors. There is no right and wrong, there is only life. The nature doesn't know what is right or wrong. Humans created those terms and try to fit everything into those categories.
P.S. I seen this quote over a year ago somewhere, so saved it and only now found time to mention it in the blog.
