This presentation uses a simple but powerful visual of black and white balls to explain how our actions create ripples that influence the world around us. The speaker describes white balls as kind words, helpful gestures, and positive choices, while black balls represent harm, cruelty, or selfish behavior. Each action, whether good or bad, sets off a chain reaction that reaches further than we can see. The talk encourages listeners to be intentional with their daily decisions, reminding us that we all carry the power to spread hope or hurt. It is a call to choose wisely, knowing that even the smallest act leaves a lasting mark.Stepping onto the TEDx stage is no small feat, but for Tosin Adebayo, it’s another exciting opportunity to lead, inspire, and spark thought-provoking conversations.
