No, I am not in desperate need of this like some others are, but some of the strategies in these books are actually very good. It's all about improving. Everyone can use improvement.
For example, like most guys, I'll get a little nervous about approaching a girl if I wait too long to talk to her and especially nervous about approaching a girl in a group. The trick is to move in within three seconds of making eye contact so as not to work yourself up into a nervous frenzy and to not freak her out by constantly staring her direction while you work up the courage. Also, when approaching the group, there's different angles to take and not take and you aren't supposed to approach the target, but rather the obstacles.
It's all interesting stuff.
