This is a very hard lesson I learned. Be careful in how you spend your time. We always are going to get a very rewarding feeling from being busy. And it is going to be answering emails, taking phone calls, and doing marketing. But, if you do not actually evaluate the impact that all this busyness is having on your return on investment (ROI) and what the income is. How are you actually making progress? Are you growing your audience? If you are a podcaster, what your income or profit is. Whatever it might be. If that's not growing or changing, yet you're busy all the time, then you need to reevaluate and perhaps implement different strategies.
