I disagree. The hard problems in math, science, and engineering are not amenable to a "fail fast" mindset. They take years, decades, or sometimes centuries of study to solve.

This sort of puzzling through play is good for solving math contest problems that have been specifically designed for the purpose, and little else.

Simple examples may be useful. Exploring them, proving stuff about them it is how one may carve a foothold to solve a harder problem.
