Firstly, I think we rotorheads are all mad for having chosen a profession that gives little in return for the first few years, but takes a lot in those inital stages. Regardless, I fought my way through with a lot of pain though, and lots of expenses.
Referring to your question if you are "Mad" or not; on one hand if you already have a job, trade, whatever, I would not give it up. Particularly, the next question that arises is; what happens if all your money is spent on flying but you still do not have the desired job? Think a bit more logical. I don't know if there is somebody else on this forum sharing my view, but if you really want to fly you should do it though be prepared for a difficult journey. Thirty-two is maybe not too old for being that "Mad", but take a word of advice: "Don't give it all up." Your current job might pull you through if there is no permanent helo job in sight.
Good luck in making your decision
