Did any one leave research field to other job opportunities and decide to return ? I am surggling to know what I really want.

Hi. You have posted before that you think of doing a PhD. I would advise to go ahead. I do not know personally someone moved from research to industry then back to academia. The reason is that they usually settle and get a decent pay with a stable job. What is then the motivation to leave the job for a Postdoc temporary job depending on the availability of fund?
But anyway, anyone can move from any field to another. From industry to academia. There are no boundries.
