I would have to say that my biggest mistake was probably quitting my job before it was time to do so. I have always had the same one site that
I have today (never really had the desire to create another). But with this particular site, I had spend so many man hours on it that I was basically getting little to know sleep... basically falling to sleep at work during the day (lol). It had gotten to the point where I had to make a choice... either the website or the job. Well... I chose the website, and without a doubt, have paid dearly for it. Because the site wasn't at the point where I was really ready to do that yet.
