German is very close to my home language which is Afrikaans.
Direct translation from Google:
had done a lot of sports so I'm very tired today. "" German is important, so I have to learn it
My translation to Afrikaans:
Ek het vandag baie sport gedoen so ek is baie moeg vandag. Duits is belangrik so ons moet dit leer.
For us, we could leave the "so" out of the sentence and say: Ek het vandag baie sport gedoen. Ek is moeg. OR we could say: Ek het vandag baie sport gedoen, dus is ek moeg - I have done a lot of sports today, thus I am tired.
Even in Afrikaans, "so" is mostly overused, but it is not grammatically wrong either.
Same here:
Hy is so groot soos sy vader...OR... Hy is so groot soos sy pa.
