Categorize your tasks by how much value they generate for you or your company. Tasks can be assigned as either $10/hour, $100/hour, $1,000/hour or $10,000/hour.
We might think of the value of the tasks as linear, where some tasks are more important than others. But the difference in value can be huge. For example, one new product could dramatically grow the business while the minor website update might make a negligent difference.
