as human beings we store digits in a memory loop that runs for about two seconds. We most easily memorize whatever we can say or read within that two-second span. And Chinese speakers get that list of numbers – 4, 8, 5, 3, 9, 7, 6 – right almost every time because, unlike English, their language allows them to fit all those seven numbers into two seconds
As a global online business, by far most of our communication with clients occurs via email. We may email an existing client in Australia in the morning, email Letters of Introduction to businesses in the United Kingdom and South Africa throughout the day, and send out quotes to potential clients in the United States and Canada in the evening (remember – we must be time zone sensitive with our emails!).
