I love this article! Companies place so much on identifying high potential talent to exponentially grow their businesses but if mental toughness or resilience is missing from your assessment, then I agree that you are making a huge mistake.

From personal experience, I have attracted individuals with a lot of potential but who have ultimately lacked mental toughness and resilience and bailed out too early choosing an easier life instead.

There is a lot written about mental toughness but it is a hard area to probe at interview and be assured that the candidate has it. I would definitely recommend using such tools as Hogan to provide you with a thorough analysis of a person's behaviours.
