… habe einen englischen Songtext geschrieben, bin mir aber nicht sicher, ob das grammatikalisch usw. ganz richtig ist… Wer Fehler findet, bitte schreiben: When I was a little girl I thought that I will save the world, The world seemed so much eseay than now, I think (that?) at that time I was much much smarter, Cause now I am just a teenager fallen in love, a teenager fallen in love
1000 Dank im Vorraus 
When I was a little girl I thought that I will (oder: wanna, shall, should, would?) save the world,
The world seemed being so much easier than now,
I think I was much much smarter at that time,
Cause now I am just a teenager fallen in love, a teenager fallen in love
Hallo!
Ich habe mal die ersten drei Kleinigkeiten korrigiert.
Die anderen finden sicherlich auch noch etwas.
1.:
thought (that) I WOULD save the world
2.:
seemed so much EASIER than now
3.:
now I think at that time
