Mid 40's here, find something you will enjoy doing everyday, then find line of work that will allow you to do that.
I can't imagine 2 years ago you said to your self , geez I really love spreadsheets and corporate tax law
Everyday we see people at work who hate, I mean really loath, their jobs. You don't want to be that person. They are miserable every day, hate getting up in the morning, just to go to work.
