I like that! I had a similar conversation with my son once when he said that someone on the soccer field was bigger than he was and how unfair that was.
I said, “Well, in life there will always be people who are bigger or stronger than you, but you are faster. Someone might be faster than you, but you are stronger than he or she is. And, someone might be bigger, faster, and stronger, so you have to be smarter. If they are bigger, stronger, faster, and smarter, well… then I hope you are better looking.””
