Here's a simple way to create a comparison between two things, one familiar and one unfamiliar. On a piece of paper, draw a line down the middle of the page. At the top of the page write down the two things, one on one side, one on the other. On one side of the page write down all you can think of about the first thing and on the other side of the page write down all you can think of about the other. Now look for where the same description is on both sides of the page.
For example, if you are trying to explain fishing in terms of public speaking, on the left (familiar) top side of the page write down "public speaking" and underneath that write down everything you can think of about public speaking. On the right (unfamiliar) side of the page write down "fishing" and everything you can think of about public speaking. Then notice where the same or very similar word is on both sides of the page. For this example, you might say, "Fishing is just like public speaking: they both have a lot of smelly flops."
This example was humorous, and the same method works for making serious comparisons of unfamiliar things.
