The road to success often has "rest & refueling stations" known as owning up to "failing" within the journey where much is learned from the experienc, and is also to be used as a "refueling" stop as well whereby the "fuel' consists of what lessons were learned through experiencing the failure or failures and the knowledge gained...
Rested and re-invigorated enough to feel much more confident to continue their journey down the road to success!
Anyone tells you that they have never in their own lives ever failed in anything is too full of the crap that usually comes out of their rear-end and incredibly ignorant of their own denial! They more than likely don't understand the concept of humility and equate it as humiliation instead... Insecurity at it's worst!
Hopefully they'll learn about it sooner than later.
