This specimen is rare accounting for only 1% of students. They can delay gratification and stay consistent on the path of learning the language.
They can focus only on learning Arabic and they have a well-defined purpose. You won't find them starting a book and not finishing it.
They are committed, relentlessly persistent, focus on three simple things, vocabulary, listening, and conversing, they see learning Arabic clearly and progress towards fluency twice as fast.
This specimen represents 99% of students. They study books for years the wrong way. Their plans rarely exceed this month.
They misunderstand the "learning Arabic to understand the Quran" concept so they try and study the technicality of the language first, then try doing everything to make sure they cover all the bases.
They see seeking knowledge as a giant knot of chaos. So after a few years of studying the language, they still can't communicate and lack understanding.
