It’s not that you can’t write, you just stop too soon
Over the years as a creative and technical writer (close to 30!), I have noticed many excuses that people give for not writing well. “I am too wordy,” “I just don’t know how to start,” “I hate writing.”
A lot of people I now work with struggle with English as a second language and I am amazed at how well they do speak and write (I have some training in ESL and have tutored English on and off for many years). English is hard! And not logical.
