This perseverance speech by Mark Victor Hansen is incredibly inspiring. Mark uses positive energy, advice and anecdotes to encourage people to possess a never-give-up attitude when trying to accomplish something in life.
Mark uses examples from when he was trying to get his now very successful book series Chicken Soup for the Soul published. He explained how it was an arduous process that required thick skin and a never-give-up attitude. He even went onto describe how he actually would forfeit long needed holidays just to do everything he could to succeed.
The perseverance speech uses a couple other anecdotes, which carry the similar message of how with the mindset of never giving up you can accomplish anything.
