G.k. Chesterton said this quote
“ The moment we care for anything deeply, the world - that is, all the other miscellaneous interests - becomes our enemy. Christians showed it when they talked of keeping one's self unspotted from the world; but lovers talk of it just as much when they talk of the world well lost. Astronomically speaking, I understand that England is situated on the world; similarly, I suppose that the Church was a part of the world, and even the lovers inhabitants of that orb. But they all felt a certain truth - the truth that the moment you love anything the world becomes your foe. ”
