Michel De Montaigne said this quote
“ And in this we must for the most part entertain ourselves with ourselves, and so privately that no exotic knowledge or communication be admitted there; there to laugh and to talk, as if without wife, children, goods, train, or attendance, to the end that when it shall so fall out that we must lose any or all of these, it may be no new thing to be without them. We have a mind pliable in itself; that will be company; that has wherewithal to attack and to defend, to receive and to give: let us not then fear in this solitude to languish under an uncomfortable vacuity. ”
