Expansion of the original point: Finding various "loopholes" in the "laws of nature" that would allow FTL/perpetual-motion/infinite-scalable-free-energy/[insert-absurdly-surreal-technology-here].

I did that from age 16 (initially as a bored-by-this-math-class-let's-think-about-something-else tactic, gradually becoming more serious) onwards to around 19, when I finally realize that the "loopholes" aren't actually in the laws of nature, just in how shitty our (or in many of those cases, mine specifically) understanding of them is.

If there exists any loophole in the laws of nature such that something impossible becomes possible through this loophole, then the map was upside-down, and it was a feature of the laws of nature all along; the laws of nature had always permitted it, we just didn't know how. The Universe doesn't rape itself.
