I was excited when I saw a monster-size sweet potato and immediately purchased it for dinner. I bought a regular sized one for my housemate, thinking that I got the good end of the deal.
But, after we cooked them, his had perfect consistency and was a delicious treat. Mine was so big that it never cooked thoroughly, and the more I tried to soften the inside, the harder the edges became. Instead of being the centerpiece of my meal, it was a big disappointment.
I think the sweet potato can be a metaphor for greed. It may seem wise to go for the gusto and grab the biggest resource, but more is not always better. Think twice before trying to lay claim to an excessive amount of anything. Humility is an underappreciated virtue.
