Writing Power Up Until Writing Power Maximum

A kid said something interesting that stuck with me. He was walking up the hill with all the English teachers and somebody commented on how great it is that he is always speaking English with the native speakers. He said, "English power up until English power maximum." I knew he played guitar and I asked him if his guitar power was maximum, and he said "Yes, guitar power already maximum." I told him I didn't think I was maximum at anything. Modesty power is maximum, but that's about it.
