I remember in undergrad I took a class and the topic of the day was the concept of an inflection point. The way the professor demonstrated it was like this: Based on time spent and potential earnings forgone, a Bachelor's degree is a good investment. A Master's is a good investment. The inflection point happens, and a Phd is not as good of an investment. That's all the information I needed to decide to stop after a Master's. Have only regretted it once, when I worked at a company that was owned by someone with a Phd in Economics and with many Phd Economists working there. I felt like a second class citizen and in a moment of irrationality, when the entire employment universe seemed to consist of only this company and ones like it, I thought about going and getting a Phd in my late 30s. Thank God I didn't. Making about 2.5x as much as I was making then, two jobs later, no further education needed (other than Cloud Guru courses).
