Oh my gosh, I made sooooo many big mistakes! Mistakes that cost me money, or time, or good reviews, or stronger networking ties or any dozen other painful costs that you could think of. Perhaps the greatest error that I made, one that came back to bite, nibble and gnaw at me regularly was not paying for a basic proofread and edit. It cost me in reputation and several negative reviews (ouch*). However at the time of pre-press I had already broken my set budget and was determined not to do so again – but if I had been willing to dig a little deeper in my pockets for an extra £400-£800 it would have been an investment well made.
