## Summary

• To find solutions to problems, it might be a better idea to invert the problem.
• Charlie Munger popularized this method, taking a leaf out of mathematician Carl Jacobi's maxim "Invert, always invert".
• This concept can be applied to investing - think: "what could go wrong in this investment?".
• As Buffett and Munger found out, success in investing is more about avoiding losers, than finding winners.

Inverting a problem to find solutions is a concept I heard from Charlie Munger. Inspired by the mathematician Carl Jacobi, he said:

Invert, always invert: Turn a situation or problem upside down. Look at it backward. What happens if all our plans go wrong? Where don't we want to go, and how do you get there? Instead of looking for success, make a list of how to fail instead - through sloth, envy, resentment, self-pity, entitlement, all the mental habits of self-defeat. Avoid these qualities and you will succeed. Tell me where I'm going to die, that is, so I don't go there. - Charlie Munger

Warren Buffett has a similar take:

Charlie and I have not learned how to solve difficult business problems. What we have learned is to avoid them. - Warren Buffett

Munger says that the best way to achieve success is by avoiding failures. He implies that it is not brilliance that made Berkshire Hathaway succeed. They consistently avoided stupidity.

It is easier to avoid failures, than to strive for success directly.

Looking at problems and scenarios from a different perspective helps us to identify obstacles in a better way.

Step-by-step guide to inversion

We can summarize inverted method to problem solving as below:

1. Figure out what you want to achieve.
2. What do you don't want to happen? This is the worst-case scenario.
3. How could the worst-case scenario happen?
4. How can you avoid the worst-case scenario?

Let's look at some real-life examples:

How to drive safe? By avoiding accidents. How do you avoid accidents? Here is how:

1. Maintain the car properly, including brakes, tires etc.
2. Ensure that the rear view mirrors are correctly aligned for your view. Ensure that your blind spots are covered as much as possible.
3. Do not over-speed. Also, control emotions.
4. Do
