翻译 - 巴西葡萄牙语-拉丁语 - Força de vontade

Hi Alex,
Your translation is not bad. I just suggest tiny changes:

1. Deus fidesque visque voluntatis --> Deus et fides visque voluntatis (it just sounds better)

2. me vincere docuerunt.--> vincere me docuerunt.
The order is crucial in this case, because "me vincere docuerunt" would be interpreted as "(they)taught how to win me".

Thanks a lot
