"It’s rare to find a place and a group
of people where you can think and be.
With so much pressure to do, to be active and productive, the respite provided by GISC is invaluable. The opportunity to reflect, recharge, and retool means that when I return to the world of doing I’m much more effective. I’m equipped at my core so that my actions are informed, not by a mechanical knowing but by a deeper understanding of myself, other people, and the world around me.
