If you add in all the extra hours it takes to prepare for your job,
commute to your job, relax after your job, and all the job associated costs
(commuting, more expensive lunches, dry cleaning, "decompressing"), your real
hourly wage is a lot lower than you think. Then afterwards, you can enter the
costs of 5 different consumer items to see how many hours it takes for you
to "earn" them. Time is Money, and Money is Time.
