Here is a link to a very short video where Norman Geisler talks about logic: https://www.youtube.com/watch?v=k06FoGmz8i4
The title of the video is "Why Is Logic So Important?"
I own a copy of Geisler's book, Come, Let Us Reason: An Introduction to Logical Thinking by Norman L. Geisler and Ronald M. Brooks. It is a good book, a rigorous book. I recommend it.
I read a book as a child on logical thinking and it changed my life. I think I was still in elementary school when I read a book my father had that introduced me to syllogisms. That brief study of logic has influenced my thinking to this day.
It amazes me how little things my parents did have made such lasting impressions on me.
