"You are not worse for your association with the world, but it is better for its association with you."--Oathbringer
Or if you are okay with a longer one:
"Life before death.
What did the saying mean? That men should seek life before seeking death? That was obvious. Or did it mean something else? That life came before death? Again, obvious. And yet the simple words spoke to him. Death comes, they whispered. Death comes to all. But life comes first. Cherish it.
Death is the destination. But the journey, that is life. That is what matters."
--The Way of Kings
