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

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

toi 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 suivant best thing.

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

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