Always invert your question

    If you have any difficulty problem, you could invert your question. This method was inspired by Charlie Munger and German mathematician Carl Gustav Jacob Jacobi, who is well known for some work on elliptic functions. Many hard works can be solved when they are addressed backward.

    For instance, HDI substrate was requested to reduce their line width and space for more I/O requirements. It is not a good solution with the traditional subtractive processes, it would like to invest more new equipment and run different processes with different new materials. Given the major cost and technical challenges, the subtractive process is still far away from adoption for the line/space 30/30um solution. To inverse this problem, by contrast, the process can start from CCL, and then using copper reduction process, the problem has been solved from other points of view.

     By inversing some questions or problems, you could think about what you could do that would discourage innovation. Ideally, you'd avoid those stupid things. 

    Avoiding stupidity is easier than seeking brilliance. Spend less time trying to be brilliant and more time trying to avoid obvious stupidity.
