This man once went out to find the purpose in his life, in a world without techonology or even electricity, a simple world. He wasn't a very sociable person, in fact he would rather be alone than in large groups of people. A thinking caring introvert. So he went out, tried a whole bunch of different things, with people, on his own, but the only thing he was actually best at was looking after animals. So he started a little farm with some chicken and pigs, but they wouldn't give him that feeling of freedom he was searching for. So he sold his Property and went on, so he became a shepherd wandering all across the country with only his sheep, his stick and himself.
Living a life free of social and economical pressure, free of being bound to one location, free from being pressured by the society, if he needed food, he went hunting or sold the wool from sheep, so he lives his life and is being happy with his sheep.

BTW: very inspiring doodles I will follow you for sure :)
