In most best scenarios, if you are good enough as developer after a few months of training you'll be able to land a job in a random software company at 1/3 or 1/2 your current salary doing probably 'boring' stuff, you know, the things that 99.99% developers do. The chances that you happen to turn out very good at programming and that you land a job doing exciting stuff that you love in a cutting-edge company are virtually zero. You may have an idealized picture of what developers do. You can try and learn some programming in your own time (yourself, with tutor etc) and see how it goes before taking the plunge.
