I recommend an audiobook course from Audible called

The Philosophers Toolkit: How to be the most rational person in any room by The Great Courses https://www.audible.com/pd/The-Philosophers-Toolkit-How-to-B...

It teaches you mental models on how to think and find a solution to a problem. It explains the concepts behind each model quite well.

Topics include how to determine a valid argument, an iron clad argument, using heuristics to solve problems, among other things.

My only gripe with the course I linked is that it is an audio version of what seems to be a video version on the Great Courses website. You might want to check that out too.
