Daylighters?

I know things can be tough for many people but a story about daylighters caught me by surprise. Daylighters are those people that are working two jobs at the same time. An example given was a cocktail waitress that worked her graphics design job when her shift was slow. Many people are risking their livelihoods to make a living. I look at this situation as someone running up the down escalator with their shoelaces untied – there’s a good chance they will get tripped up. The issue I see is that these people are working two linear income gigs instead of finding one that gives leveraged residual income like the company I work with. Now, I control my life while working on a part time basis.
