Owner ship of IFR capable airplane and acquisition of IFR flying skills is a great idea but it's not a quick job and some people just don't hack it.
Best preserve your ambition and start slow and simple, concentrating on first principles and basics. Perhaps buy and sell two airplanes during these early days, commensurate with your progress and skills level. I do not think investment in an advanced airplane is a good idea for a zero time pilot, as a starting point.
