What they really mean by 'Broaden your horizon.'

      An important concept in learning anything is in the understanding that it happens in plateaus, or levels. To illustrate this, let’s take a look at something called the Dunning-Kruger Effect. In essence, what it says is that a person who knows a great deal about a subject is likely to underestimate their skill and knowledge, and conversely, that same person will likely overestimate his knowledge on something he knows little about. Consider the old saying, “The more I learn, the less I know.”
      For example, in massage therapy, after getting a license, the therapist is required to take Continuing Education classes once every two years in order to keep the license valid. A new therapist who needs to take a CE class might say to himself, ‘My certification class already taught me about anatomy and technique, so I think I’ll study Reflexology for my requirements.” Another student who decides to further study technique instead, will find that there is a lot more knowledge to be gained that was simply skipped over in the original class, just for ease of explanation.
      Certification courses will very often exclude lessons on massaging around the neck and spine, simply for liability purposes. If Student B hadn’t taken a following class in neck and back massage, he may never have learned a more complete view of the same subject.
      Indeed, The phrase, ‘field of study’ is more precise than most would imagine. Every subject is a veritable landscape of knowledge, appreciated fully only through intrigue and exploration. Climbing these learning plateaus is the scholastic equivalent of taking the high-ground.
      In language, this could mean not just learning vocabulary, but the very formations of a modern language.
      For example, many of you may already know that English is a Germanic language that comes from the Saxons et al. This is why words in German and English are to this day astoundingly similar. ‘Hund’ means ‘Dog (hound)’; ‘Sonne’ or ‘Sun’; ‘Komm hier’ for ‘Come here.’ Even the English days of the week come from Norse Gods, not Latin. Wednesday is from Woden’s Day, Thursday from Thor’s day (consider the French word for Wednesday, Mercredi or Mercury’s day).
      But from the Norman invasion of England in 1066, the aristocracy and the ruling class of England was replaced by the French speaking Normans, causing a linguistic revolution! The language of higher learning became French, and so we have an incredible mixture of both in the modern English language. The modern word Sun is Germanic in origin, but words we use in its scientific study are Latin. We say, Solar flares, or Lunar eclipses (the words in Spanish for Sun and Moon are ‘Sol’ and ‘Luna’).
      As in the earlier massage therapy example, it would be like saying, “Well, that college Spanish class taught me enough vocabulary to get by. I think I’ll start learning Thai.”
      There is always more to learn. After a certain level, just reading a book about Spanish won’t help you make new friends in Mexico. You have to get out there and use it. Remember what Niels Bohr, Nobel Prize winning physicist said, ‘An expert is someone who has made every possible mistake in a very narrow field.
