Yesterday, I overheard two colleagues chatting in the company break room. One said, "My salary is too low; I do so much work and only get paid this much. It's really unfair." The other said, "Yeah, I need to talk to the boss and ask for a raise." I was thinking at the time that these two might be confusing one thing—the salary is not their value; it’s just the price they sell their time for. This might sound a bit confusing, so let me explain.
