Would just like to comment that as ever, Scroggs offers sound and well informed advice. Trying to guess where the market is now is a futile exercise. A far better option would be, as Scroggs quite rightly suggests, to do your training and give yourself the best possible chance for employment at the end of it. But only do this if you feel very motivated and prepared for the inevitable hardships.
My personal advice would be to check your own finances and their health, and also take some form of aptitude testing (like the GAPAN tests), have a deep think about whether this is the job you want, and go for it.
