Who are we quoting here, exactly?

A few weeks back, someone sent me this quote in a text message:

"When I got enough confidence, the stage was gone. When I was sure of losing, I won. When I needed people the most, they left me. When I learned to dry my tears, I found a shoulder to cry on. And when I mastered the skills of hating, somebody started loving me."

The attribution was to William Shakespeare. Although the meaning of the message was life affirming, I don't think it was a Shakespeare quote at all. Anybody who has a passing interest in or a cursory knowledge of Shakespeare's works would realize that the writing style is not like Shakespeare's.

It seems the Internet can't place the source of the quote, either. All I get are links to sites compiling SMS quotes, most of them attributing it to Shakespeare.

A version of this quote was posted to a blog in February 2009 (probably the earliest version of the quote I could find online):

"You know when I got enough confidence to present my view about the matter on the stage, the stage was gone. But when I was sure to lose, I won the stage. That is called as life."

It may be that the blog owner was the one who wrote that passage. Or they were quoting it from a source that is unknown to us. I don't feel like spending more time figuring this out and will leave the next literary nerd to figure out the answer.
