I second Brutha's advice. If you are like most people, it's probably easier to lower your standards than to raise them. So start off with really high standards. If you meet a girl who you really feel is healthy for you, but she fails one of your qualifications, then decide how that will affect the relationship and whether or not you can or should forgive it.
Try to stay objective, too. I know that advice will probably fly out the window when romantic attachment enters the picture, and I've never been in a romantic relationship so my advice is pretty much second-hand at best, but I do know what it is like to lower your standards for someone else.
