Few words of positivity

If you can walk with the crowd and keep your virtue, or walk with Kings-nor lose the common touch; If neither foes nor loving friends can hurt you; If all men count with you, but none too much; If you can fill the unforgiving minute with 60 seconds worth of distance run- Yours is the earth and everything that's in it, And-which is more-you'll be a man my son.

Rudyard Kipling, If: A Father's Advice to His Son
