The illness, and the untimely death of my brothers, has made me conscious of the fact that - rather than just think about it - it’s crucial that you do today what you want to do.

Gibb frames personal bereavement as a catalyst for urgency. The illness and early deaths in his family (especially among his brothers) collapse the comforting assumption of “later,” turning intention into a moral and practical imperative: act now. The quote contrasts passive rumination (“just think about it”) with embodied decision (“do today”), suggesting that authenticity is measured by follow-through rather than aspiration. It also implies that grief can yield a clarifying perspective—one that reorders priorities toward meaningful work, relationships, and self-expression before circumstances foreclose the chance. In this sense, the line functions as a memento mori translated into everyday resolve.
