Fortunately, my Mother was a Reading/Writing and English teacher, and she helped me with those basics.
In my senior year in high school, my home room teacher was an excellent English teacher. She and my Mother enabled me to ace my two college English courses. Which were all, I needed in 5 plus decades of life.
Flash forward a few decades after my college years and one of my sons is in high school, and he wrote a paper that was terrible in English but got him an A in a tech course.
I told him, he needed to study some basics in English. He informed me that he would hire a good secretary when he finished college in engineering.
He did, and she is now his executive assistant. She has been with him for decades. He is a vice president in a heavy duty real tech world. She does his reports/bid proposals now, as she did then. He provides the tech know how, and she puts it into a written format.
When I finished my MBA except for my thesis, I went to a lady whose business was to put into a book the ideas of the MBA student. I paid her a good 4 figure price at that time. Between the two of us, we did a great job. She had a Masters in English and couldn’t find a job. So, she did the finishing work on her husband’s masters and prepared and excellent thesis from his research. After that, anyone, who didn’t use her services, usually didn’t do that well.
It must be nice to hire underlings to speak and write decent English for you!
I prefer to learn the basics myself.
