Many excellent people have freed themselves from all distractions. They've given up wealth, business, and pleasure to spend their entire lives learning how to live well. Yet most of them die admitting they still don't know how to live — let alone how to live wisely. Believe me, it takes a great person who rises above human weakness to protect every moment of their time. That's why their life feels very long — they dedicate every possible part of it to themselves. No time sits idle or wasted or under someone else's control. They find nothing worth trading their time for, and they guard it fiercely.
Many excellent men have freed themselves from all hindrances, have given up riches, business, and pleasure, and have made it their duty to the very end of their lives to learn how to live: and yet the larger portion of them leave this life confessing that they do not yet know how to live, and still less know how to live as wise men. Believe me, it requires a great man and one who is superior to human frailties not to allow any of his time to be filched from him: and therefore it follows that his life is a very long one, because he devotes every possible part of it to himself: no portion lies idle or uncultivated, or in another man's power; for he finds nothing worthy of being exchanged for his time, which he husbands most grudgingly.
