“Treasure your childhood”
Now how exactly should I do that?
I’ve never actually met anyone who felt that they “treasured” someone or something sufficiently, and perhaps it is because no matter how hard we try, we can never fully "treasure" anything (time, people, places, etc.). Even if we are aware of how fleeting and important such things are to us, maybe we will never be satisfied by the degree at which we had "treasured" it (or them).
Perhaps it is because we recognise how much we miss what has been lost such that we realise no matter how much we had "treasured" it would never have been enough.
