Think about it. Try naming one historical figure that made a difference by playing it safe and being average. The vast majority of successful people are remembered for the difference that they made in their lifetime. And that difference required them to take risks and challenge the status quo.
We are inspired by people who go beyond the norm and push the boundaries of possibility.
Mediocrity, on the other hand, does not inspire. Nor does it lead to greatness, salvation, or purpose. Success, however you define it, will elude you unless you are willing to push the limits you have placed on yourself and that others have placed on you.
