It’s more than a hobby. More than a “post apocalyptic life skill”, though there is some truth to that one!
There is a story about Pablo Picasso that I have no idea if it is true or not, but the “moral of the story” is valuable nonetheless, so I will recount it loosely: Pablo was sitting on a park bench sketching, when a woman sat down. After observing him for a few minutes, she asked if he would draw her, and he agreed. After showing her the sketch he told her it would cost $5000. She was appalled, exclaiming “That only took you 5 minutes!” To which he replied, “My dear Lady, it has taken me over 50 years of study and training to be able to do that in 5minutes.”
