Parshas Yisro - Excitement vs Inspiration

When Yisro joins Moshe Rabbeinu in the desert, Moshe relays all of the happenings that occurred to Klal Yisrael. This despite the fact that the passuk already tells us that Yisro had heard everything. Why did Moshe tell Yisro what he already knew? What was being added? Rashi tells us that Yisro heard about the splitting of the sea and the war with Amalek. This is difficult to understand since the passuk tells us that Yisro heard everything that happened. Why do Chazal highlight these two events? In this shiur Rav Burg explains that difference between excitement and inspiration. Excitement does not last but true inspiration which comes from relevant education lasts a life time.
