Monetary Value of Time

We all have some idea of how much our time is worth. On extreme ends, it is easy to know if a task is worth your time. For instance, if someone offers you $0.07 per hour and another $7,000 per hour, you would have no problem to decide.
However, in the middle of the time-value spectrum, it is less clear if a particular task is worth your time. While everyone has an hourly value, few people know the exact amount.
