Black, White, and Gray Zones
There's an influential book called The Power of Full Engagement that discusses energy management. My takeaway from it was that, with managing your energy, it's better to be “fully on” or “fully off” than somewhere in the middle, which is where most people spend most of their time.
My philosophy on successful podcasters is very similar—you will have more success picking a side, regardless of which side it is, than being in the middle.
