grit

An inherent, positive non-cognitive (meaning mostly unaware) personality trait that enables perseverance through otherwise difficult or impossible obstacles over a long period of time without the loss of passion and is the resolve that requires courage to mold strength of character as a driving force to successful and often self fulfillment. It is often combined with the definition of resilience.
