I studied Law and became an English Solicitor. However I was not from a family that had powerful connections and found it very hard to get a job in Frum/Jewish or big corporate law firms.
So I ended up working for a few years in non Jewish small firms and Local Authority Legal departments.
After a losing my job a number of times, I decided to abandon the profession and join my father in the clothing manufacturing and wholesale trade.
I would advise to look carefully at what you Father or Grandfather did for parnosoh and whether that has application today.
