Sorry, realized you asked in English:
Yes, in German it's unevitable to use personal pronouns, which is not the case in e.g. Italian or Czech (and Greek?), where the conjugation of the verb "includes" the personal pronouns, and tells you explicitly who is doing s.th.
I read (english)
Ich lese (deutsch)
but
leggo (Italienisch)
čtu (Tschechisch)
