During his keynote speech at World Domination Summit, the comedian / actor / writer Zack Anner openly expressed his gratitude for his best friend. Since Kindergarten, this person has been a constant companion for Zack (who has Cerebral Palsy & is wheelchair-bound). As result of the love of his friend, Zack has had opportunities, experiences and joys that would have otherwise never been possible.
Zack then set a homework task for everyone in the audience; think of someone who was there for you at some point in your life—someone who helped you grow—then, during lunch break call them, and thank them.
I called my Mum.
