Have a fine capability to use precise words for the concepts or feelings that come up in your mind. It doesn't have to be in english if your mother tongue is not english.

Modern writing is bland. Everything is "great". Everyone says "I feel great!". But great could mean a lot of things. It doesn't give the listener or reader a specific idea of what you're saying. It's worse to tell yourself that you're feeling great. Your body may not accept it as the word "great" represents no specific emotion or feeling.
