A man who was unemployed for several months gets a job with Public Works painting lines down the center of rural roads. The supervisor tells him he is on probation and that he must stay at or above the set average of 2 miles per day to remain employed. The man agrees to the conditions and starts the next day.
The supervisor checks and finds the man completed 4 miles. "Great," he thought, "this man will work out." The next day he finds the man only did 2 miles but the supervisor thought, "well he is still at the average and I don't want him to get discouraged."
The third day however the man only did one mile and the Boss thought, "I need to talk to him." The boss pulls the new employee in and says, "Son, you were doing great. The first day you did four miles and the second day two miles, but yesterday you only did one mile. Why? Is there a problem? An injury, equipment failure, anything keeping you from meeting the two mile minimum?"
The man replied, "I keep getting farther and farther from the bucket."
