Carrot keeps me honest and on track. You get a sense of accomplishment when you complete a task and see the points she gives you. You get more points for tasks that have been on your list for a long time, and that gives me a sense of recognition, too. I know Carrot isnt sentient, but the developers do a good job making you suspend disbelief.
