Eric Nehrlich is an executive coach, and was formerly the chief of staff on the Google Search Ads team. Before becoming chief of staff, Eric was part of the team that got Google's revenue forecasting down from an error rate of 10-20% to an error rate of around 0.5%. We open up with some wild stories of Google's early attempts at revenue forecasting, and then dig into how that forecasting success happened. Along the way, Eric explains how he, his boss, and his team developed a fingertip feel for variation in data.

We then switch gears to talk about Eric's coaching practice. We discuss the differences between mentorship and coaching, and talk about the tricky art of helping leaders grow their impact. Eric has a wealth of knowledge on coming up with small experiments in order to make personal growth easier. We talk about how he comes up with those experiments, and what some of those experiments look like in practice.

Finally, we close with a chat about Eric's upcoming book.
