Nobody wants to fail. We’re shamed (usually unintentionally) starting as children until we develop an aversion to failure. Spilling the milk as a clumsy toddler turns into not applying for a promotion as our developing child minds become adult. We avoid failure, or rather, the chance of failure to protect ourselves from the degradation it might bring upon ourselves. If we don’t try, we don’t fail, and that’s the safest thing to do.
