The time to labor is while it is day. - Petrarch

Co la morte a lato
cerco del viver mio novo consiglio,
et veggio 'l meglio, et al peggior m'appiglio.

And what good has all your reading done you? Out of all the things you have read, how much has really stayed in your soul, what roots have grown there that will, in a good time, bring forth fruit? Examine your heart carefully. If you compare the whole of what you know with what you don’t know, you will find that your knowledge is like a small stream dried up in the summer heat compared to the ocean of your ignorance. And even granted that you do know a lot, what difference does it make?

So süß klingt allen Menschen das Wort Freiheit, dass selbst Keckheit und Frechheit überall Anklang finden, weil sie mit der Freiheit einige Ähnlichkeiten haben.
