When??

When?? this kind of word has haunted me for several times behind. I've found some sentence which said " if you find your true love, don't give up on it ~c huck bass in my facebook friend profile and I'm getting my self to understand it. And till' now I still don't get it.

my conclusion is just " don't give up to love someone that we care about, but don't push to hard to get him or her...because we can love them even we don't have them as part of our life indeed ".

but my question about it is When we must stop our self try to catch her or him?? sometimes we don't know or we don't wanna know. Because our feeling has blinded us....and we get our self more egoistic among it.
