Up until recently I taught the “newbies” at my company. I’ve become very discouraged by the lack of real “education” that these people are receiving–as you have noted, the real cost of business, the planning that it takes, etc.–that I couldn’t with any good conscience do it anymore.
It took me six months to make my first dime, and it was barely $150 by the time the past ARs and bills were paid. I succeeded only because of a lack of mental sanity and a lot of guidance from my fiancé. Would I do it again? Not sure, but hang in there!
