Denis Waitley emphasizes that successful individuals are often motivated by a deep inner passion rather than the pursuit of wealth. This intrinsic drive fuels their determination and commitment, enabling them to overcome challenges and achieve their goals. Passion acts as the core element that propels them towards success.

In Janet Bray Attwood's book, "The Passion Test," this concept is further explored, suggesting that true greatness comes from expressing one's inner self. The idea is that by following this internal calling, individuals not only fulfill their own potential but also contribute meaningfully to the world around them.
