I thought you were sure he was an ILE?
Take a look at the advice you were given in the thread you made for career advice for an SEI through the fresh eyes of your new LII typing? You posted your own interests and skills there.
Better yet google search the types of careers you are interested in and then look into what it would take to set yourself on that path. Look into getting a career counselor. They should be intelligent enough to help you out. https://www.thebalancecareers.com/ho...-coach-2059777

If you ask for advice under various self typings people probably won't take you as serious, unfortunately.
I don't think you would enjoy the types careers some LIIs here have since you already said as much in other threads.
