This could be a PhD topic: training full time is a matter of opportunity and necessity (perceived) but with all the best intentions fulltime training is not the best option for everyone. Some need the distraction of work or study - the intellectual stimulation. Work/study can also provide a pressure valve; can provide a safeguard against overtraining-induced injury, illness and/or staleness. But sensible programming can be enormously productive for the right fulltime athlete, at least in the short to medium term. However many fulltime athletes are kidding themselves into believing it is the only pathway to success.
