This sounds kind of simple, but the first thing to learn would be how to read animal sign. Go out in the woods and streams where you live and start observing what is going on there. Look for tracks and scat and other signs. Look for beaver houses and muskrat huts. Look for trails. Try to get a good idea of how animals go about their daily lives.

Because you can have the best trapping equipment in the world, and use the best lures made, but if you don't set the trap where the animals are, you won't catch anything.
