This is how it works. You finish your medical degree then you start your year hospital placement. At the end of that 12 months you can start applying for training positions. Surgeon or Psych whatever tickles your fancy. If you get a training position straight away you can expect to be fully qualified by early thirties at the earliest. Once qualified you will be on 150 a year min. This will rise quickly. The average taxable income in 2013 for a surgeon was 300k.
The only way you would be walking the wards for 10 years is if you got continuously rejected for every training position you applied for.
