"The learning capacity is limited by the number of languages an individual knows," is a theory that I read a while ago. I will be trying to remember the author of that phrase, but I remember that he had very good arguments to defend his words.
In any case, all knowledge serves to grow and be a better human being.
I wish you good cheer and the best of luck.
Thank you very much. I am trying to learn basic Spanish as fast as I can
