I heard this phrase from an acquaintance once and over the years the profundity of it has “hit home” many times. The “things” of life are temporal; your job, your car, house, real estate, toys, gadgets, furniture, clothes, gizmos, etcetera. The relationships you have and the ones you make are of lasting value. Your jobs, titles, and prestige will come and go, but the people who you interact with can and will be attached to you for the rest of your mortal life. This, especially, includes family relationships. Fight hard to keep, maintain, and in some cases, reconcile your relationships.
When in all boils down, as the saying goes, “it’s who you know, not what you know” that counts.
