Almost. You did well, but it's too hard for me, except maybe for short phrases like this, which, regardless, still requires effort well above my comfort. It's the sixth most used letter by some measures. Seek out the typesetters' placeholder phrase where the first "word" has it as last (sixth), place, before the successor "SHRDLU", which show the order of the most used letters of, uh, latter-day British? Oof. Edit: Modified to avoid a superfluous usage.

This hurts, so it's time for me to stop.
