> First, there’s not really other jobs I’d rather do.
I suspect there are many jobs you would do, but you have to allow yourself to let go of the dreams, the ambitions, the identity you have built in academia.
A few years ago, almost seven, I decided to leave academia, after a PhD and many years as a post doc, more than 50 journal papers published, awards and recognition in my field. I loved doing research, writing papers and thinking about the new advances I would make.
Why the change of mind and career? First, it seemed that my time as a researcher had passed, and that I was becoming an old postdoc with little appeal to universities and research institutions. Second, I was growing tired of earning little money. Third, it was beginning to look like I was doing similar research to what I was doing 5 years earlier, and I had a feeling that it would be the same research I would be doing 5 years down the road.
I started interviewing for positions in (tech) industry, got a monetary offer 5 times what I was making as a senior postdoc, started a new career, and never looked back. The last part is not entirely true.
At times, I look back and regret the last 5 years I spent in academia. I could have had a faster career in tech, earned much more money, and would have met bright and motivated people sooner. The world is full of interesting technical problems that need to be solved.
