No need to quit your job or move to Italy. Turn notifications off on your phone, get an espresso machine for your home, buy some decent table wine. Get the books you want to read and start reading them. Go to the library on the weekends. Arrange to get to/from work on public transit and your commute turns into reading time (90 minutes a day for me).

I have a full-time job and read as many philosophy/sociology and math books as I ever have. You can actually try out your plan of full-time study on your next vacation - I bet you will bore of it in three or four days.
