I'd liked to have trained as a doctor, though I would have some difficulty with cutting flesh and giving injections. I'm sure, however, with good training I would get over these difficulties and 'enjoy' the process of bringing diagnosis and healing to the sick. It's a great profession, though doctors do work very hard and sometimes for long hours. The satisfaction in helping must give its rewards, however.
There's been loads of things I'd have liked to do in my ideal fantasy life, but most of them are totally unrealistic. Perhaps the most realistic is the one which led me to join HubPages. I'd love to write for a living.
(Of course writing hubpages is one thing, but I guess my first choice would be writing film scripts, and my second would be travel writing. Dream on!)
