No Such Thing As Bad Student

Spoken by Mr. Miyagi (Pat Morita) in The Karate Kid (1984), written by Robert Mark Kamen. The line directly challenges the Western habit of blaming students for poor results and instead places the burden of responsibility squarely on the teacher. It is consistent with Miyagi's broader pedagogical philosophy, which emphasises the mentor's role in crafting the right environment and method for learning. In context, the line also functions as a quiet self-standard: Miyagi holds himself to the highest possible bar as Daniel's teacher.
