Songs. My, my ...they either make us cry or laugh. Such a wide range of emotions in music.
Let me tell you a short story. Early on just after Ms. Wonka moved out, I watched a biography about Mary Pickford and I cried at the sections when she and Douglas Fairbanks fell deeply in love....AND divorced in the end. Gosh! Turned on the waterworks for sure.
Thanks for the info about your work experience and background. The first thing you would want to think of are what we would call "transferable" skills. Those are the skills you can carry over in any other industry.
Another thing you might want to keep in mind about your transfer skills are the sustainability of a certain field. For example, the oil industry is reliant on fossil fuel which is starting to go by the wayside slowly but surely. It is something for you to think about when assessing your next job. You don't want to wither on the vine that is no longer plentiful.
In the foreseeable future, there will be an explosion of digital imagery such as X-rays, etc as more and more of the healthcare services are migrating to virtual files (and nearly paperless).
Other sources to look at are the local business journals. They contain chock full of information of area businesses and movements such as recent hires, M & A. Beside business related information, they usually contain info on networking nights. You might want to take advantage of them! You might want to scour the local library and look up business journals. It also won't hurt to take a look at the local Chamber of Commerce for opportunities as well.
As Eric suggested earlier, look into consulting. In Boston, the largest consulting company was Boston Consulting and Bain. I can only imagine that Houston and cities close by would have a consulting firm or two that has personnel with your background and expertise. The beauty of working for a consulting company is that it is not entirely reliant on sales or commissions.
