mindfulness

"At what time soever thou wilt, it is in thy power to retire into thyself, and to be at rest, and free from all businesses."

"It is not that we have so little time but that we waste so much of it. Life is long enough, and it has been given in sufficiently generous measure to allow the accomplishment of the very greatest things if the whole of it is well invested."

"Hold every moment sacred. Give each the weight of a lifetime, and keep it as your own."

"The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly."

"Confine yourself to the present."
