It's important to note that hourly wages have really only been around since Henry Ford and the assembly line. Ford needed people to do very easy but boring, mindless tasks all day long and the best way to get them was to guarantee their paycheck.
As we have moved from a manufacturing society into knowledge society (and hourly jobs are being outsourced) many people are now paid for their performance.
The only way to guarantee your paycheck in this realm is to actually do the work instead of standing around the water cooler. What a neat concept!
Don't be afraid of commission work. Soon it will be tough to find an hourly or salaried job. Instead, embrace the concept, do the work and reap the benefits.
