“Never stop because you are afraid – you are never so likely to be wrong.”
“Never keep a line of retreat […] it is a wretched invention.”
“The difficult is what takes a little time. The impossible is what takes a little longer.”
“The history of the human race is a continual struggle from darkness into light. It is, therefore, to no purpose to discuss the use of knowledge; man wants to know, and when he ceases to do so, is no longer a man.”
– Fridtjof Nansen, Norwegian explorer, writer
