John pitches in on the Dip from about.com: Podcasting: Radio Reinvented.
I've already been profoundly affected by it, if the measure of "profound" is that I've begun changing my behavior. Many times while reading through this, I resonated with the idea of knowing when to quit as also being the ability to say no. Not just to specific projects or even people, but to behavior that tends to lead me down a rabbit hole where I don't get anything accomplished. I'm actually really good at time management (I work from home and had to learn to do so effectively out of self-preservation) but having the idea of 'the dip' elucidated so well has really helped me.
