It's useful to know what each of those terms means.
Your motivation is for a specific task or goal.
Expectancy is your confidence that you can complete a task or reach the goal.
Value is the importance you assign to the goal.
Impulsiveness is how distractable you are, or your susceptibility to other interesting things that you might do instead of working toward the goal (like writing comments on HN! ;).
Delay is the amount of time you have until the task should be completed.
The more distractable you are, and the more time until you hit your deadline, the less motivation you have.
The more confidence you have in your ability to complete the task, and the more importance you assign to it (eg this is life or death), the more motivated you are.
Motivation = (Expectancy + Value) / (Impulsiveness + Delay)
