"Today is yours." You must seize it because it is fleeting, only twenty-fours hours that are soon gone by. If you live to be eighty years of age, you will have only 29,200 days. Each of them, therefore, is a precious fragment of a gift called time, your time. It only makes sense to use every day well. Today is yours. Use it well.
- Norman Vincent Peale
"Measure your health by your sympathy with morning and spring. If there is no response in you to the awakening of nature, if the prospect of an early morning walk does not banish sleep, if the warble of the first bluebird does not thrill you, know that the morning and spring of your life are past. Thus you may feel your pulse."
- Henry David Thoreau
