What worked won't work.
Everyone wants tactics.
"How did you do that?"
They want to know the exact words you used, or the brushstrokes you painted, or the way you fed your starter.
What we tend to overlook is that tactics are useless without the underlying theoretical understanding of what's happening.
Sure, they might work for a bit, and they might get you what you want in the short-term, but especially in an information-rich environment like the one we live in now, the market rapidly gets flooded with armies of people doing the same thing—red ocean.
Not to mention that there are so many confounding variables that go into literally any tactic that when you take it out of its specific context and environment, the whole thing falls apart.
My wife loves to make sourdough. She's been going at it for a little over a year and is getting really good. Recently, we moved to a new country where the weather is significantly different than where we were before—different humidity, altitude, temperature, etc. Her starter, which was thriving in our old home, began to flag and die (they're finicky little things). Saving it wasn't about specific tactics (feed it exactly this much at this time at this temperature) but rather learning to understand the particular starter in front of her and the deft application of a few principles.
Principles are so much more intriguing as a knowledge-base to build than tactics, because principles are timeless, whilst tactics are old the first time you use them.
Take communication, for example. There are so many variables that go into communication—the emotional state of the people talking, the medium through which they're talking, the topic they're talking about, etc. It's almost impossible to share exact scripts for a particular thing because they're so context-dependent. But what we can do is identify some principles, some elements which are the same in all conversations, with all humans.
All of life is like this—there are a few key underlying principles which then are expressed in different ways. Our biology even works this way! Our DNA is comprised of four chemicals which come together in a limited number of ways—principles. But in conjunction with one's environment (and according to new research, mental state and the way we live our lives), these genes express themselves in a myriad of different ways.
That's why creativity is valued so highly—we always need to be doing new things to outrun the ossification of the present.
This is why humans have to create. If we don't, if we're not adding value to the world in some way, if we're not expressing the principle of humanity in a new variation—well, then we've become just another outdated tactic.
