I would suggest that things are different these days. There is an awful lot more red tape to deal with than in your Dad's day.My dad did it, who I have a great admiration for, at the same age as I am now, and his business thrived, trouble free until he retired at 64, as a car mechanic. He is of the "Fred Dibnah" breed of mechanics that would stop at nothing to make a living
In our industry there are the professional memberships to be considered, liability insurances (which are hellishly expensive especially if you work with gas and brazing / soldering / welding etc) and things like annual calibration of test equipment (which again isn't cheap), vehicles and insurances, and all that sort of thing before you actually earn a penny. It is the overheads that cripple many businesses and it isn't getting cheaper.
My qualifications are that I have been self employed, and for me it didn't work. However, Peter Jones (Dragons Den) lost it all on numerous occasions before hitting it big. I wouldn't mind being a fiver behind him these days.
