It's part of the habit to try to keep track of how many words one reads, writes, speaks, and hears/listens, for me both as a student and a teacher of the English language. I used to tell everyone to spend 10,000 hours at least on reading and listening each, and try to write emails or something else in English at least once in a day and read only serious things with focus and interest since it seemed what most 20-year-old students were reading to enhance their reading skills were short fairy tales meant for babies.
I read somewhere - mostly Speed Writing and Speed Reading books I found around 1990 - and Wikipedia that an average educated person of the United States reads English at 200-300 or 600-1,000 WPM and an average person speaks about 10,000 words in a day. Those statistics cannot be accurate as most people can't guess how many words a daily and weekly issue of the New York Times or the Fortune, or an unabridged copy of Les Miserables contains.
It's been one of my principles to do teaching always for free and to do translation always for money. Confucianism taught me never to receive something in payment from students and learners because it's a sin and make the teachers corrupt. Experiences taught me it does more harm than good to students of the English language to help their translation studies and homework while most South Korean students and workers tended to depend on translation by others rather than trying to find the original sources or trying to read the original things if available.
I thought about posting this thread while composing an email reply. Computers, games, and later smartphones as well have done a lot to make people read and write less, but it's much worse in Seoul. I guess an average college student and white-collar worker among 20s and 30s in Seoul spends more time playing mobile games than writing with pens and typing with keyboards. It now seems most people don't write anymore except when they are forced to do so at workplaces and classrooms. A lot of Westerners can type at 80 WPM or a little over 1.3 WPM and a day has 86,400 seconds so a truly prolific writer should be writing at least 10K or 20K words each day whether it's a book to be published and printed or nonpaid web articles.
A few years ago, I translated more than 10,000 words in a day, but the rate was very low (one tenth of the usual Western rates) and sometimes I was typing 30K to 50K words in about 30 to 40 hours. During the late 1990s, I probably was always typing since I posted hundreds of posts each day on hundreds of web communities - least productive thing I've ever done.
