Understand your goals and go for them

Two boys I know used to love to hunt for snakes in the fields adjacent to their home. They grew up in a rural area, and from early childhood until late adolescence, they would hunt for snakes in the fields two or three times each week. They would go into the fields and start turning over rocks and sticks and boards at one corner of the field and move in every direction and cover every square foot. They would turn a rock over and quickly look to see if there was a snake to be caught. If not, they immediately moved to the next rock or piece of wood or debris and turn it over just as quickly. If there were no snake to be had, they would move on to the next rock.
