One major role of a coach and therapist is to align expectations to reality. It is our job to be a more objective lens. An experienced guide that can see past the clients limitations in perception.
At time this is the role of the hype man/woman. Building confidence to allow them to see their potential. Showing them that they truly are resilient and adaptable. Allowing their perception to match their innate or trainable capabilities. Here we must put them in situations to succeed.
At other times, we must show them failure. We must take them safely to the task that they cannot yet manage. We must show them that despite their perception, they are just not quite there yet.
It is our job to titrate the experience. To align expectations to reality. To keep it real.
