Certainly, it can be very difficult to adopt such a stance. But, it's not impossible.

As humans, we respond and learn and continue to adapt to all sorts of circumstances, both new and continuing circumstances. That's the way we grow and evolve.

So, if one finds it difficult to be transcend one's emotions, to overcome one's fear, or to be stoic in the face of adversity, that's just a sign that s/he is still growing and evolving.

And hopefully, it will motivate the person to grow and evolve consciously.
