> If we roll with the average Adsense income, here’s the bottom line: $14k going out. $4k coming in. Net loss, month over month: TEN THOUSAND DOLLARS. That’s a lot to sink into a channel that is barely moving book sales and not getting me a TV deal. Simply put, it’s completely unsustainable from a business perspective.
Why carry on doing that for so long?
