“In 1835 the celebrated French philosopher Auguste Comte wrote, of the stars: 'We shall never be able to study, by any method, their chemical composition or their mineralogical structure.'
"Yet even before Comte had set down these words, Fraunhofer had begun using his spectroscope to analyse the chemical composition of the sun. Now spectroscopists daily confound Comte's agnosticism with their long-distance analyses of the precise chemical composition of even distant stars.”
Don't be so quick to dismiss something, someone. Don't open your mouth to say that 'this can't work', 'this person is lost', 'all hope is lost'. Don't even think 'I'm a failure', 'I am finished', 'he will never change', 'that door is locked'.
Because at that point that you are making that assumption, someone else is out there, giving it a try, pushing that door, doing his best.
And you know what? He just might succeed where you only saw failure.
