Marcel Proust said this quote
“ We do not receive wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can make for us, which no one else can spare us, for our wisdom is the point of view from which we come at last to regard the world. The lives that you admire, the attitudes that seem noble to you, have not been shaped by paterfamilias or a schoolmaster, they have sprung from very different beginnings, having been influenced by everything evil or commonplace that prevailed round about them. They represent a struggle and a victory. I can see that picture of what we were at an earlier stage may not be recognisable and cannot, certainly, be pleasing to contemplate in later life. But we must not repudiate it, for it is a proof that we have really lived, that it is in accordance with the laws of life and of the mind that we have, from the common elements of life, of the life of studios, of artistic groups—assuming one is a painter—extracted something that transcends them. ”
