What's u never know how much u cherished something until its gone mean?

It just means u didn't know what u had until u didn't have it any more, u didnt' see it while u had it, but once u didn't have it any meer u realized what u missed... So I guess it also means appreciate what u have now cuz it could be gone tomorrow. :]

u have to keep 2 things in mind:
1. We want what we can't/don't have.
2. We get easily bored and want the volgende best thing.

When u say that u don't know how much u cherished something until it's gone, u mean that when u own it u do not fully appreciate just how great it is until u no longer have it.

It might of might not mean that they cherish something more. It all depends on the context of the situation and just how fickle that person is.
