"The fountain of content must spring up in the mind, and he who hath so little knowledge of human nature as to seek happiness by changing anything but his own disposition, will waste his life in fruitless efforts and multiply the grief he proposes to remove. "

"It is common to overlook what is near, by keeping the eye fixed upon something remote. In the same manner, present opportunities are neglected, and attainable good is slighted, by minds busied in extensive ranges, and intent upon future advantages. Life, however short, is made still shorter by waste of time; and its progress towards happiness, though naturally slow, is yet retarded by unnecessary labour."

~ Samuel Johnson (1709-1784)
