How some people manage to pity me

I have recently come to a startling but unsurprising and even obvious conclusion: in true love, I am basically looking for a clone of me.

I don't mean that completely literally. I admit that I have flaws (!), as it would be impossible for me to be 'perfect' in my ideal. So my potential true love could be slightly different from me, since I differ from what I ideally want to be. But the principal idea still stands.

As I have attempted to state many times previously, I want to be the best and greatest person ever. So this raises the question, how can I be the best and yet have an equal person as my true love? I will not have a lesser person as my true love, so this leaves three options:
i) By a grand coincidence, there exists one, and only one, other person in this world who is a perfect equal to me, and I will meet them and they will be my true love.
ii) I accept that I cannot be the greatest person ever.
iii) I become asexual.

This scares me, because options ii) and iii) would be tragic and option i) is overly romantic and completely unrealistic.
