How does love emerge? What does it take succeed in love?

It depends on what kind. sibling love is when 2 or more siblings have a strong bond with each other. It really is the same with parents. Romance love, now that's hard I guess it emerges when people go out with each other. Best friends can become a boyfriend or girlfriend relationship. The only way to succeed in love is when you actually love the person you love because of her characteristics, not her looks or fame. People may be mean at first but it's most likely something happened to them. Then there's lust. Lust is when 2 people want each other but don't love each other. True love is only when you and your love been thru a lot with each other and are still together.
