Try it here: list what you know for sure
Write down the few things about this problem you are sure are true, so you can rebuild your thinking from them.
What do you know for sure about the physical and cost limits of this build?
Practices that may help
- First-Principles Thinking, Made Usable
First-principles thinking means breaking a problem down to the fundamental truths you are sure of, then reasoning back up from those — instead of reasoning by analogy to “how it’s usually done.” Traceable to Aristotle and popularized in modern form by figures like Elon Musk, it is a reasoning discipline, not a tested intervention; its value is mechanistic — it strips out inherited assumptions. - Reason up from the parts, not by analogy
Build the solution from the fundamentals you kept, rather than copying an existing template.
First-Principles Thinking, Made Usable - Deconstruct the problem to its fundamentals
Break the problem into the few things you actually know to be true, with no inherited conclusions.
First-Principles Thinking, Made Usable - Rebuild from fundamentals and stress-test it
Reassemble a solution from verified parts, then attack it to find where it breaks.
First-Principles Thinking, Made Usable - Prototype — make it cheap and real
Build the roughest possible version that lets you learn something specific.
Design Thinking, Step by Step - Use Socratic questioning to test each belief
Interrogate every claim with “how do I know this is true?” until only bedrock remains.
First-Principles Thinking, Made Usable - Define the ideal final result first
Describe the perfect outcome as if the solution already exists and costs nothing, then work backward to what could enable it.
TRIZ: Systematic Invention and the Logic of Contradictions - Challenge: systematically question why things are done the way they are
Ask "Why must this be this way?" for each element of the problem — not to be contrarian, but to find which constraints are real.
Lateral Thinking, Made Practical - Use inversion as the first model in every problem
Before solving a problem, ask what would guarantee failure — then avoid those things.
Mental Models: Charlie Munger’s Latticework Approach - Calibrate whether the problem requires invention or just search
Determine whether your problem is already solved elsewhere before investing in original invention.

Does this sound like the set of challenges you might be facing?
- Every idea I come up with is basically a tweak on what someone’s already done
- When I list out everything I “know” about this problem, half of it is really just how everyone says it has to be
- I’ve got this fresh idea I’m genuinely excited about, and that excitement is making me go easy on it
- The idea lives perfectly in my head so I keep refining it there and trusting it more and more, but it’s never once touched reality
- There’s this thing I’m treating as obviously true and building everything on top of
