The motivation to complete a task relies on four elements:
Expectancy: If you expect to succeed at a task, you’re more motivated to complete a task before its due date.
Value: If you don’t value the task, you’re more likely to put it off.
Impulsiveness: It’s common to feel anxious about the unknown. However, when we act on these emotions it can distract us from the things we need to accomplish.
Delay: The longer you have to wait to be rewarded for a task, the less motivated you are to complete said task
