If I had my time over again I would train as a draftsman. A lot less study time and you still get to design things. have input into clients designs etc. I usually use one of my guys plans that has passed council for an overall footprint, then I design it how I want, but he has some fantastic input into my designs both inside and out. I would think there is far less time involved in studying but you still get to be creative and draw things up. You can then run your own little business even from home if you wished and make money from patios, garages, etc.
