It may be a cultural thing but I rarely find this style of poster motivating. More often I find it demotivating that an employer or co-worker has the gall (or perhaps naivete) to expect to influence my personal motivation through an arbitrary aphorism pinned to the wall. I enjoy witty and insightful as much as the next person but would not wish to work at a place where truisms decorate the halls. I'd rather have scenery and nice paintings, thanks all the same.
