I am proof. it also proves the point of this word, which is one of my themes for the year, and especially this upcoming week. "Tenacity" means to me that you keep going about something until it eventually works. Trial & error strategy is the main one employed, w/ a fair amount of repetition. You can tell that i started with the 'T', not knowing how exactly to go about stitching a word, and ended with the 'Y' looking like I perhaps had some small inkling by the end....the others letters subtle-ly increasing in confidence as i went along. Try this at home, kids.
