As McAero rightly says, this is more or less down to you. You must surely have a strong interest in one specific area.
Flying and engineering are massively different, and are also a million miles away from an executive job in an airline boardroom.
But, If you have the bug for aviation (the same as myself), and you feel a sickness every time you see an aircraft overhead - then get yourself into the industry. It really is as fascinating as it seems..............
