Using PDF in Spoken and Business English
A lot of people get a bit “lazy” when sending documents. If you want to impress someone in a business setting, go the extra mile and make a PDF of the same material. The content won’t be any “better” but it will appear better if you send it in PDF form. It appears that you spent more time doing the research and it makes the document appear more valuable.
There are many programs that convert regular text documents to PDF files and they are easy to find online.
This is just a psychological phenomenon that really works well in the real world. In English, we have a saying, “don’t judge a book by it’s cover”. It means basically that we should judge the inside content instead of the pretty packaging. The interesting thing is, however, that no matter how hard we try, we can’t help ourselves. We judge things on appearance whether we like it or not. I sold a lot more stuff on one website just by changing the design. It made people take the website more seriously. This is the same idea here.
The truth is that often better content really IS available in PDF form. I’ve made several free ones to help people with their English speaking. I’m going to point you to one article that I wrote and feel free to follow the links and download the free material that I’m sure you’ll find helpful.
