Mary Shelley Quote

But he found that a traveller's life is one that includes much pain amidst its enjoyments. His feelings are for ever on the stretch; and when he begins to sink into repose, he finds himself obliged to quit that on which he rests in pleasure for something new, which again engages his attention, and which also he forsakes for other novelties.
