What a fine and inspiring essay. I was introduced to the stoic philosophers as a college freshman. At 18, much of their wisdom went right over my head. Later, after more life experience, I began to value their lessons and learn from them. It's always good to be reminded of the truths you point out in this wonderful article. Thanks for writing it.
By the way, regarding the money your relative scammed from you, there's an old saying: " Bread cast upon the waters will come back to you after many days." You gave with a good and generous heart. That's the main thing. This goodness will come back to you, perhaps when you least expect it, and may very well be magnified.
