Drive to action that (as opposed to intrinsic motivation) springs from outside influences instead of from one's own feelings. The children had an unjust teacher with many extrinsic motivations, such as good grades and gold stars for good behavior, and detention for being noisy, on the other hand. My friend had been dealing with a lot of extrinsic motivation because he had been dying to win the lottery and become rich.
Brick Walkway Costs and Considerations. A professional will charge something on the order of $8 to $15 per square foot (or more) to install a brick walkway. For a basic 25-foot long by 4-foot wide walkway, thatâs an estimated cost of $800-$1,500. The labor required to install a brick walkway is a major cost determinant.
In the case of a particularly complex walkway and/or decorate brickwork, donât be surprised if costs balloon to as much as $30 or more per square foot. The bricks themselves are another major cost factor. Depending on the size, shape, and quality of the brick, costs range from $.50 per brick to $3.50 per brick.
