Citizens of the World. Seneca, Epistles 3.28.3-4

Seneca tells Lucilius how to live, and travel, well: we must quiet the mind, allowing it to release the burden of attachment (addicere, cf. addiction) that makes particular events painful to us. When we release this burden, all places become home to us, because we are at home in our minds, free to be here without worrying about what is there, and vice versa.

Vadis huc illuc ut excutias insidens pondus quod ipsa iactatione incommodius fit, sicut in navi onera immota minus urgent, inaequaliter convoluta citius eam partem in quam incubuere demergunt. Quidquid facis, contra te facis et motu ipso noces tibi; aegrum enim concutis. At cum istuc exemeris malum, omnis mutatio loci iucunda fiet; in ultimas expellaris terras licebit, in quolibet barbariae angulo colloceris, hospitalis tibi illa qualiscumque sedes erit. Magis quis veneris quam quo interest, et ideo nulli loco addicere debemus animum. Cum hac persuasione vivendum est: non sum uni angulo natus, patria mea totus hic mundus est.

Right now you are thrashing back and forth, moving here and there in an effort to cast off the burden that weighs upon you, and making it even more uncomfortable to bear as a result. Like a ship, your mind carries immobile cargo better; when its load is distributed unevenly, a toss is sufficient to send it sinking where the most weight gathers. Whatever you do right now, in this bad condition, turns against you, harming you with your own motion. Careful how you beat the sick man that you are! But when you have successfully disposed of your mental burden, every change of place will become pleasant. It will be possible then for you to sojourn well in all the ends of the earth. No matter what strange corner of the world you light upon, it will become a friendly home to you. Your identity as a traveler matters more than whatever recommends any given destination, and so we must attach the mind to no place in particular. We must live convinced of this belief: “I am not born from just one little region: my homeland is all this world.”
