One example of a short quote about life is, "In the end, it's not the years in your life that count. It's the life in your years," from Abraham Lincoln. Another example is, "The purpose of our lives is to be happy," by the Dalai Lama.
Abraham Lincoln was the 16th President of the United States during the 19th century. He led the United States during the Civil War, and his actions helped end slavery, save the Union and modernize the economy. Lincoln was largely self-educated, and before becoming president, he was a lawyer in Illinois. He also served in the Illinois House of Representatives for 12 years. In his iconic speech, the Gettysburg Address, Lincoln supported the concepts of nationalism, republicanism, equal rights, liberty and democracy.
The current Dalai Lama, Tenzin Gyatso, is the 14th Dalai Lama, as of 2016. Traditionally, the Dalai Lama is a monk from the "Yellow Hat" school of Tibetan Buddhism. In this school of Buddhism, the Dalai Lama is the successor from a line of tulkus who are believed to be reincarnated forms of the Bodhisattva of Compassion. Another short quote from the Dalai Lama about life is, "Our prime purpose in this life is to help others. And if you can't help them, at least don't hurt them."
