The problem with that video is in the title. Star pilots my arse...Especially the First Officer that calls himself Captain
Regarding flight training, start now if you wish but do it modular and keep your day job, don't get into debt. Start at your local aeroclub and after the PPL sign up at an ATPL ground school. There is plenty of time to begin your CPL-ME-IR modules at the right time after you will have passed ATPL exams. 36 months if I remember well.
