Moshe was a Shepherd

Shemos (03:01) Now Moses, tending the flock of his father-in-law Jethro, the priest of Midian, drove the flock into the wilderness, and came to Horeb, the mountain of God.

 Rabbeinu Bachya (Shemos 03:01) And Moshe was a shepherd. Moshe chose this profession as was the custom of the early tzadikim as we see with Abel the son of Adam as well as our fore  Fathers and their children. The reason being to be far removed from settled areas which provide opportunities for sin and also to have solitude to achieve prophesy.
