Consulting is so interesting to me. I love that you can make more than your base salary.
I have a small technical expert practice on the side. It is nice to have an extra source of income. However, the schedule is both unpredictiable, unforgiving, and I have very little control over it beyond accepting or turning down any particular engagement.
I once asked one of the partners I was working with how he planned vacations, becuase it was impossible to know when he'd be free. "Oh, it's actually easy. I set my vacation for the week originally scheduled for trial, because I know for sure that's the one week trial will not happen."
So easy to think the grass would have been greener had you chosen a different specialty/profession in life
In my field, the "academic financial penalty" is steep. When I graduated, private industry paid about 1.5x-3x more than academia did. Now it is more like 5x-10x, and it can be higher for certain sub-disciplines. A colleague resigned his tenure line a few years back while I was the department chair to take a senior architect job at one of the FAANG companies. He did not give me a number, but described it as "baseball player money."
I often interview faculty candidates who are considering both academic and industry positions. What I tell them: "As a professor, society makes the following bargain with you: You will live a comfortable but definitely not extravagant life. In exchange, you can pursue whatever you think is the most important path for teaching, research, and service."
For some people, that's a more than fair bargain. I know it is for me. But, to be happy in this, one has to adopt an attitude of "this is enough." The alternative is keeping score with money. Since that's a game that is impossible to win, it's pretty easy to be miserable no matter what Line 11 says on your 1040.
