The answer may surprise you. It turns out that volunteering is not related to wealth or income but to a style of framing perceptions about the value of time. Once you start working hourly, or billing your time by the hour, you start to be conscious of the value of time.
I’ve noticed this response when people shift from free lancing to take a regular job, or “J.O.B.” They’re very conscious of the way employers waste their time. For instance, one friend was putting together an online program. She was told to, “Check the links to be sure they’re okay.”
“Aren’t there computer programs to do that?” she asked. She was shocked as she considered the value of time she was being asked to contribute to this mindless task that a low-cost piece of software could accomplish more accurately.
Going the other way, new entrepreneurs often have trouble making sure they use each hour effectively. “Time is money” takes on more meaning when you aren’t drawing a fixed salary.
On the other hand, some people move to the other extreme. They are very conscious of how they spend personal and leisure time as well as business time.
