Invert the Problem

One of  things Charlie Munger is well-known for is his principle to 'always invert'. Was trying to understand what this technique was about. He has some good YouTube videos explaining how he uses it.

As far as I can tell, it works something like this.  If you wanted to figure out how to ensure your project ends up successful, you should invert that problem and ask, how can you make the project fail? If the project fails, then it cannot be successful. If somehow you can prevent it from failing, then you have increased the chance of making it successful. 

Understand the causes of failure, and then prevent them and avoid doing them.  In addition to how you can make the project fail, think about what else can make the project fail, and then plan against them. The latter is more risk management though.
