…that you don’t know what you got until it’s gone.
Or maybe you don’t know what’s possible until something has gone away or changed. Or what you’re capable of until a big change or a choice has been made. Even if it wasn’t your choice at all. The latter is especially fulfilling.
Perhaps for some, you can only find out what’s better and see the positives by going through the negative.
If you only think of what’s gone, what didn’t happen or could have been, you’ll never be able to focus on what can be. Or the great things that are happening in the present, right now.
