I too have aspirations of moving into other fields. In my case I am a programmer with a keen interest in space and aeronautical engineering. I also have a family, mortgage and all the fun that comes with said responsibilities.

I recently read about the Learning Transfer method (https://trainingmag.com/improving-learning-transfer). In a nutshell you increase your chances of success by applying skills learning in vastly different industries. So perhaps you should find ways of leveraging your past skills , transferring that knowledge and skillset into another industry.

Keep trying to reach that goal but don't loose sight of what it took to get where you are now.
