"Don't look for love...let it find you."
I think that is the most pessimistic statement I have ever heard. It sounds like something a person that has "failed" too many times in their pursuit of love says to justify being too afraid to try again. If you want that great job, do you wait for the CEO to approach you, or do you put yourself into the "pool" of sharks and make them believers as to why you are the best for the position?
I think finding true love is the same way. Even when the world is seemingly still, it is still moving at a rapid pace. Light seems constant but does it not move as well? Just because you don't see the "wheels" in motion does not mean that they are not moving.
Love is the same. How can you possibly find love if you are both standing still, waiting for each other? In a matter of fact, how will you know who you are waiting for? We'll wait our lives for someone to come along and all the while realize that we have been duped. I don't feel that we are assigned a single soulmate. With that being said, the possibility of finding the "right one" is infinite (or pretty good at the least).
You shouldn't expect life altering things to happen if you're too afraid to take risks. So instead of asking why is it taking so long for love to find us, shouldn't we be asking ourselves, why are we being so lax in our pursuit of love?
