Sounds odd to me, even without switching from "el que" to seas. I probably would say "lograr (o ganar) ese premio no significa que uno es el mejor en este campo". But wait for a native. :) - bosquederoble, May 17, 2016
Welcome to SpanishDict. You need to add the English translation. - rac1, May 17, 2016
If you want to keep the el que part, maybe something like: El que has logrado ese premio no es necesariamente el mejor en este campo. :) - bosquederoble, May 17, 2016
I want to express "That you has won the award doesn't mean that you are the best in this field" (I think it's also very weird in English, but grammatically it shoulid be right. So in Spanish, what should I say if I want to use a thing as subjetct?)) - KennisJuan, May 17, 2016
El que ha= he who has, he that has. I was wong in "El que has logrado"- that should have been "El que ha logrado". Sorry. - bosquederoble, May 17, 2016
That you have acheived- would be "Que has logrado". No el. - bosquederoble, May 17, 2016
The Englsish is fine. - annierats, May 17, 2016
