4 yr old career counseling

Do you ever notice that kid are much more interesting than adults. My 4 yr old son was driving with my wife the other day and a song was playing that included the line "Would you be the saviour of the broken?" My son asked my wife what a saviour was and she explained to him that it was a person who helped people. He asked if they helped homeless, sick and poor people and wife told him yes. My son then thought for a while and said that he would like to be a saviour when he grew up. My wife told him that would be a great idea as it is very important to help people. He then remained quiet for quite a while and my wife could see him in the rear view mirror deep in thought. After a few minutes my son said he had a problem because he wanted to be a saviour but he also wanted to be a Ninja and it is hard to be two things. In fact, he also wanted to be Batman so that would be hard and he would have to think about it because he would like to help poor people and homeless people or people who were lost in long grass because you know people who are in long grass get scared because they can't see were to go. He thought he might have to talk to his brother to see what he thinks so it should be interesting to see where this goes. I'm just glad my wife wasn't listening to If I had a Rocket Launcher.
