history: I'm not perfect but I'm always confident that no matter what I do, the only person who knows what's best for me is ME and no one else.  For that I'm grateful and always know I'm the man
current: I am confident in my own judgment.  Because I am not just a man---I am THE MAN like that 50 cent song...I'm not perfect but I'm always confident that no matter what I do, the only person who knows what's best for me is ME and no one else
next: Do you trust other people at all?  It seems like it would be hard to trust someone if you think only you can know what is best for you.
