Principles are ways of successfully dealing with reality to get what you want out of life.
Ray Dalio, one of the world’s most successful investors and entrepreneurs, cites principles as his key to success.
In jazz, there's no script: You have to figure things out as you go along. Sometimes you need to sit back and let others drive things; other times, you blare it out yourself. To do the right thing at the right moment you need to really listen to the people you're playing with so that you can understand where they're going.
All great creative collaboration should feel the same way. Combining your different skills like different instruments, improvising creatively, and at the same time subordinating yourself to the goals of the group leads to playing great music together. But it's important to keep in mind what number of collaborators will play well together: A talented duo can improvise beautifully, as can a trio or quartet. But gather ten musicians and no matter how talented they are, it's probably going to be too many unless they're carefully orchestrated.
