Actually, with space technology, that goal seems too realistic. Perhaps having sex in space while jumping on a pogo stick and juggling and solving complex mathematical equations without a pencil and paper and writing the Great American novel would be a better goal.
Personally, I think another person would make it more difficult to know myself in some ways. Now I would be fine, but when discovering myself it would have clouded my judgement immensely. However, I am a rather introverted, solitary soul, so that is me. Even when I planned on the whole marriage/eternal soulmate thing (it might still happen, it's too soon to tell, but probably not), I realized my moments (definately plural, my friend; there are many moments that feel like "I've got it!" Then another one happens a few months from them, and everything keeps building and you know yourself better and better and you're a better person and it's absolutely fabulous! At least this is how it should happen.) would mostly come alone.
