To me, respecting yourself means taking care of yourself, treating yourself well, not harming yourself, basically not treating yourself like crap. And not letting anyone else treat you that way either. It means going through life with an innate sense of value, but not self-importance. If I respect myself, it doesn't mean that I think I'm God's gift to the world or all that great, but simply that I care about myself, even if no one else does.
