He who travels to be amused, or to get somewhat which he does not carry, travels away from himself, and grows old even in youth among old things. In Thebes, in Palmyra, his will and mind have become old and dilapidated as they. He carries ruins to ruins.
Ralph Waldo Emerson in Self Reliance. Pretty clear echoes of Seneca:
They undertake one journey after another and change spectacle for spectacle. As Lucretius says: “Thus ever from himself doth each man flee.” But what does he gain if he does not escape from himself? He ever follows himself and weighs upon himself as his own most burdensome companion.
