We should enjoy the gifts of our body and natural advantages carefully, without fear. But remember — they won't last long. They're only on loan to us for a brief time. Don't let them control you. Don't become their slave. These things aren't really part of who you are. Think of physical pleasures and external rewards like support troops in an army camp. They can help, but they're not the main force. Make them serve you, not the other way around. Only then do they actually benefit your mind.
If we guard the endowments of the body and the advantages of nature with care and fearlessness, as things soon to depart and given to us only for a day; if we do not fall under their dominion, nor allow ourselves to become the slaves of what is no part of our own being; if we assign to all bodily pleasures and external delights the same position which is held by auxiliaries and light-armed troops in a camp; if we make them our servants, not our masters—then and then only are they of value to our minds.
