I want to find someone who not only loves me, but lets themselves experience love and doesn't worry about the chances of things actually working out.
Relationships are like startups. If you join one because you think it will be successful, versus just joining one because its interesting, worthwhile, and its something you're passionate about--regardless of its ultimate chance of success--then you shouldn't be in one. Most relationships, like most startups, don't last forever. They're also completely unpredictable, so you just find good people, communicate well, and do your best.
