Observation (1) - the use of language.
Just listening to interviews of very high-profile managers and business men/women in my home country, I noticed their uses of language is not always good, sometimes it's hard to follow and rather ambiguous. The main characteristics of those people's speaking are: The idea is vague covered ambiguous words. Listener sometime must deduce what is being spoke. Redundant words are omnipresent. The sentence tends to be long. The overall information is low. Sometime it's waste of time to listening to interviews/speakings without much information. I realize that to reduce my wasteful time spent on speaking non-sense things in your future, I should take time to study carefully my mother tongue.
