Why learn German?
German is an extremely useful language to learn. It is one of the top languages used in career fields including science and business, and is the most frequently spoken language in the European Union. Additionally, German and English are from the same parent language, so many words are similar!
My philological studies have satisfied me that a gifted person ought to learn English (barring spelling and pronouncing) in thirty hours, French in thirty days, and German in thirty years.Mark Twain, “The Awful German Language”
