Great post, I definitely support this kind of material. Gets you thinking. Upvoted.
I really dislike repeating myself and try to resort to the use or application of various words around a central topic that is synonymous in relation to one another. That is also a bit fun for me to work my way around a maze of different phrases to reiterate what I am trying to convey. There is a way to repeat yourself but if used in variation, I believe it to be more subtly effective as not coming off as desperate or too condescending/or superior (especially repetition within dialogues/discussions/or debates).
