The Wild Man

Grimms the Wild Man starts with a boy getting independent from your parents. Disobeying the kings (who is also his father) orders is his first step to get away from his parents - a decision that is just followed by another much further reaching decision that makes him finally independent from his parents. Instead of taking his fathers punishment, which would probably not have been as bad (he would have be beaten), he chooses to leave the protection of his fathers kingdom and goes with a complete stranger. It seems as if he consciously tries to get away from his paternal safety and start his own life in a world he doesn’t know and understand yet. Still, taking the risk of leaving ones parents definitely is the advice for young men this story conveyes.
The second advice is how to get a wife. He takes a job and starts working. But instead of working on his own, the wild man does all the work and all he has to do is to take care of his appearance – which finally also guarantees him the princesss attention. Paired with his refusal to take her money and giving it to the wild man instead, we can see three basic manners how men should be: they should take care of their appearance, they should be willing to be only rewarded for the work they do which is basically honesty, and generosity, as he gives the money to somebody else even though he could have needed it himself. All these points finally influenced the princess to marry him.
Even though these features helped him convincing the princess, he couldn’t convince the king and the queen. He had to war to be accepted and appreciated by them, which is probably the final advice for young men who want to gain success in life. It reminds me of the rags to riches story: the only possibility for a regular man to be accepted by the higher society probably was great services in war. Thus military service was another important factor in a mens education.
