When I was freelancing a bit over a decade ago I was making more than most people my age I knew at the time. My natural reaction was to try scale that, so I hired folks to do the work for and with me... that is when I learned first hand how difficult it is to scale a services-based business.
However, folks much smarter than me taught me another thing. True wealth is created when you reach a point where you are making money while you are sleeping - which is exactly the opposite of what I was stressing about ("I only make money when I am charging for my time"). Ironic.
