The document discusses effective communication skills. It notes that technical jargon should generally be avoided when speaking to non-technical audiences like grandparents or novices. Texting is not appropriate for a job application or formal letter, while a personal statement could include some informal language. Constantly checking the time in an interview is a bad idea, as is using a monotone voice or reading directly from a powerpoint when presenting to an audience. Engaging an audience involves making a joke or speaking enthusiastically rather than using a monotone voice.
