And I'm sure there are more that I use on an almost daily basis, but those are the only ones I could think of right now. Those little blurbs that you see every day, the ones on fortune cookies, the ones from movies, the ones that just stick in your head from whatever source, they are the ones that have meaning to you for whatever reason. Whatever they are you keep them and use them all the time. Just remember to get rid of the negative ones and stick with the positive ones!
