After yesterday's inspiring lecture by the amazing (and supercute) Fabio Novembre, I think I found an answer I was looking for since many years.
He told us: 'Your home is where you choose it to be'. 'There you could reinvent yourself. You should live yourself whereever you live.'
...Well, I should've known... since I do believe that "Home is where your heart is". The only thing that you really have to listen carefully to your heart and there you'll find the answer where is your home.
