Well I used to work in the semiconductor industry before giving it all up to go and self fund my CPL.
I spent £32K getting the licence and then got a job after 2 years. I now work for a well known UK regional operator. I earn £22K per year slogging my guts out doing 6 sectors a day, 5 or 6 days a week and have virtually no time to pursue any leisure interests. The annual pay increments for FO's in my company are less than £400/year.
If I could wind the clock back I would have stayed in my very well paid electronics job and flown for fun in my spare time.
You must remember that being an airline pilot must be one of the most over rated jobs going. The money isn't all that good and its bloody hard work flying for the regional operators.
However only you can make the decision as to go for it or otherwise. Whatever you decide good luck.
