I am getting ready to write a persuasive speech about to become a surgical technologist. How should I open my speech with impact?

Personally, I enjoy analogies that highlight the
job.

For example, "Remember the medical TV shows you'd
watch and the surgeon would always say 'sponge' or '10 cc's of sedative, STAT!' or
'here, hold the retractors open here; this is going to get fiddly'. Well, these jobs
belong to surgical technicians, who are always right up in the action zone.
Interested?"

Or something. I dunno, just a thought.

Have fun writing!
