The greatest glory in living lies not in never falling, but in rising every time we fall.

Falling is only really an advantage if we overcome it. We learn humility from the event. But also we gain success that gives us a tried and tested quality that can only come from falling. There is no other way!

To be honest one often must take quotes in context.  At that moment in time. To those he was speaking to. He was contrasting with those who may think real success is never falling.

Maybe another day he would say the greatest glory in life was his grandchildren. So it often is about the moment to be honest. It fitted in then and for his audience .
