Nothing is drearier than just always telling the truth about yourself. Rousseau, who as far as I can tell was a pathological liar, made this wonderful distinction between lying, which he said there was something wrong with if you were trying to extract an advantage for yourself or evade responsibility for some nasty thing you'd done. But if all you're really trying to do is impress or keep it young or make life more vivid and interesting, go for it! There's no real harm in doing something like that. I think people can be overly saddled to the truth.
