@Evildevil4787,
Introspection as a word choice is a less than optimal choice. It’s not a grammatical issue, however. Introspection implies a person looking into one’s soul as opposed to examining or studying of words. Perhaps using something like Word Study Group, Word Sleuths or Word Detectives.
You’re correct in not choosing rumination.
Style wise, you need to study how to keep your tenses consistent and in the present tense.
Use the phrase fewer people instead of less people.
Furthermore, I’d be remiss in not correcting your usage of the phrase ‘have choose’ instead of ‘have chosen’.
