All we have is words and language to express our feelings and communicate our ideas, sharing them/communicating them with others. Hence, the importance and high roads of poetry and prose writers (especially journalists these days). They, who ‘do it all’, with just words/spoken and written language.
Looking back on all the great men and women of history, you’d have to say that words and language were key, vital elements in their many effective, popular communications.
But this idea also applies to expands via The Arts (including non-verbal communications). Those expressions, communications, and works of musical composers and performers, those of painters, photographers, and sculptors, those of moviemakers, movie writers and actors, those of dancers and choreographers, the architects and builders, and many other artists of various artforms not mentioned above.
Overall, the creators, who make new things, experiences, and possibilities for us all to explore, ponder, and enjoy in every age.
