I like this saying because it encourages that mistakes are ok to make. I expect my students to show effort in the work that they do, and mistakes are fixable and acceptable as long as they keep trying. I would put this saying on a poster (on vinyl sticker like the one here) and keep in my classroom to remind students that it is ok to make mistakes.
Ok i know this is probably ( or surely) made by photoshop But IT'S TOO CUTE, I CAN'T NOT PIN THIS. (And it's funny cause i'm Not sure if i ship them togheter... I Mean They Will be perfect togheter But i think they're only Best Friend so... I don't know..)
