Express vs Impress

I read something online recently and I was impressed. The writer wrote, "you can't express while trying to impress". Now this is super. He (the writer) was expressing, but I, the reader, was impressed.

Express and impress, what's the difference? When I communicate candidly, I'm expressing. I try to stay close to the facts and choose my words objectively. Here, I try not to add emotional or subjective feelings to the message to which I want to communicate. But when I want to impress, this is another case entirely. Impressive words dwells largely on flattery and less on factual words.

Whereas in the former I'm trying to state facts without necessarily seeking for approval, in the later, my primary purpose will be to seek approval, so facts may not really be a necessity. Now, with the meanings so clearly stated, examine your conversations with the people around you everyday - do you express or impress? Personally, I think it depends on the audience and occasion. I will definitely do more of impressing my boss than expressing myself! The bottom line of this is, both (express and impress) have their pros and cons. But if you are able to impress while expressing, you are a good communicator.
