What is my primary motivation for learning these 46 languages?

A lot of people asked how many languages I know. It is difficult for me to answer that question without knowing what it means to know the language. Everyone has a different standard of knowing a language. If I only know how to read in that language, does it mean I know the language?

I have learned many languages and writing systems separately. No wonder there are languages I can speak and writing systems I can read. The following list will show you my motivation for learning them in one sentence each. I use the first 18 languages daily, either actively or passively. So, I arrange them in the sequence of fluency, I put the rest of the languages, more or less, in the sequence based on the time I learned them actively.
