John Wayne, "Talk low, Talk slow, and don't say to much." The other quote is an all time favorite from Max Ehrman's Desiderats, "Speak your truth quietly and clearly; and listen to others, even the dull and the ignorant; they too have their story."
Oh man.. those are just awesome, thank you for sharing that with me.
If you get a chance take a look at Desiderata, it is a valuable tool I use on many occasions to put things into perspective. Have a great day!
