The best rule is to just keep it to yourself (at least until you're certain the attraction is reciprocated). Don't act on it, don't let it color your interactions or conclusions about her competence, good or bad. Its important to not objectify your co-workers, as that is the starting point of all sexism and sexual harrassment. And incidentally, since attractive women receive questionable attention all the time, your gentlemanly behavior will make you stand out, possibly allowing you to become friends or more, if thats what is mutually wanted. You will also grow as a human being.

Thanks, I was asking more in general - I think many people could need that advice. Sadly, I rarely ever have female colleagues. But I am also not in the dating scene anymore, so it is not really a problem for me to ignore attractive colleagues atm.
