I’ve just learned how learning two languages can be very stressful. Since I’ve already studied the German language, and now am trying to better my spanish abilities, I often find that learning ye ta second language can be very stressful on your brain since often I want to speak german when I’m learning spanish, and in the end everything can become confusing.
If you want to learn two languages and not just one, my recommendation is to first learn one language well before moving on to the second. Learning them at the same time could be a disaster. I did it with Russian and German and my brain never hurt more. Now that I speak fluent German, learning Spanish is easier yet still a major kopfschmerzen.
