Hahahaa. Oh dear.
Well, to respond to the OP, 'success' in such a thing as 'love', isn't so easily defined. It depends firstly, on how one defines love, and then, what determines 'success' in this said 'love'.
By my own definitions, being young, etc, I have been successful in love so far as to say that I know what it is NOT.
Now to respond to some of the ideas brought up in the continuation of the thread: INTJ women, in fact, I would say, initially have a MORE difficult time in 'finding love' than most women in general. However, if you're comparing them only within the INTJ type, as it seems you are doing, I would say that a mature, perhaps a bit older, female INTJ would have a much easier time in finding love. However, an immature, or strongly expressed (I'm not relating the two, they can be mutually exclusive) female INTJ would have a much much more difficult time than a male.
Perhaps I rambled on a bit without making entirely too much sense, but I'm sure whoever decides to read it will manage.
On that note, when someone says success in love, what does that mean to you (anyone who feels like answering), or rather, what does it imply?
