Thanks to Leandra Gebrakedan for sending me this quote from Robert F Kennedy, speaking at the University of Cape Town, SA, in 1966.
"Few will have the greatness to bend history, but each of us can work to change a small portion of events, & in the total of all those acts will be written the history of this generation [...]
Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, & crossing each other from a million different centers of energy and daring those ripples build a current which can sweep down the mightiest walls of oppression and resistance."
Overly gendered language aside, it's a lovely quote for times when you need to remind yourself how your small contribution can make a difference.
