A missing tool can teach a skill convenience would have hidden.

Convenience solves a problem and takes the understanding with it. When the tool is missing you have to learn what it was actually doing, and that knowledge stays with you afterward in a way that using the tool never produces. The gap is an education you did not choose.

When something you rely on is unavailable, resist replacing it immediately. Work around it once. What you learn about the underlying problem tends to be worth more than the time it costs.
