As a child I had either historical role models or fictional characters.
As a child it was:
Davy Crockett
Robin Hood
Zorro
Now as an adult my role models are mainly fictional. Well, all two of them, both of which are fictional:
Dr. Who
Sherlock Holmes
I realized that the two role models I have are both sort of outlandish, lonely, brilliant and full of such knowledge. It helps to make me feel less lonely associating with these characters, even though they are fictional. They are probably the two I would love to be more like. Although both tend to have devoted companions that aid them in aspects of their personalities that may be a hinderence.
As to what to ask them. I would ask Dr. Who if I could join him on his adventures, and I would ask Sherlock Holmes if I could become his apprentice.
