Mark Twain:

 Mark Twain (Samuel Clements) used to have trouble finding time to be alone. He therefore used to take his fishing pole and head to the river. Since it was considered bad manners to disturb anyone when they were fishing he found time alone to think and reflect. He didn't like to mess with fish so he never put a hook on the end of his line. He would just sit on the bank with his line in the water and have some peace and quiet.
