The primary thing when you take a sword in your hands is your intention to cut the enemy, whatever the means. Whenever you parry, hit, spring, strike or touch the enemy’s cutting sword, you must cut the enemy in the same movement. It is essential to attain this. If you think only of hitting, springing, striking or touching the enemy, you will not be able actually to cut him.
The McNamara fallacy, named for Robert McNamara, the US Secretary of Defense from 1961 to 1968, involves making a decision based solely on quantitative observations (or metrics) and ignoring all others. The reason given is often that these other observations cannot be proven.

No matter what you love to create, there is something to be learned from the way Hans Zimmer approached the Dune score. We are all striving to create work that is novel, innovative, memorable, and inspiring. To get there, however, we tend to focus on getting things right, on avoiding mistakes, on “being professional”. Yes, it is important to have the commitment, dedication, and attention to detail of a professional. But being right? That will only take you so far. What is much more important is to approach the problem in front of you with curiosity and an open mind. With an urge to explore what can be found beyond the ordinary, beyond the right way of doing things. If you want to create something that nobody has come up with yet, it is important that you try out all the crazy ideas others are afraid to try, that you build prototypes, improvise, and freely play with the materials and the technologies you have at hand.
