Translation of "Disposition" in Italian

- If only I had met more people in the past, today I'd be a different person. But, due to my introverted nature, I can now rely on very few friends.
- Had I started to socialize with people in the past, maybe I would be a different person now, but, because of the shy disposition I had at that time, now I really have few friends.

Se solo in passato avessi iniziato a socializzare con la gente, a quest'ora forse sarei un'altra persona, ma, a causa del mio carattere chiuso che avevo a quei tempi, mi ritrovo con pochi amici e basta.
