The defining factor [for success] is never resources; it’s resourcefulness.

Source: "Why We Do What We Do." TED2006. Feb. 2006. Conference Presentation. Additional Information: The meaning of this Tony Robbins quote is that the reason people fail isn't because they don't have the resources (such as time, money, etc.) to succeed; it's because they don't have the imagination and drive to succeed. The quote is from the motivational speaker's 2006 TED Talk about the motivations that drive people. In this Talk, Robbins gives the following examples of resourcefulness that you can use to succeed, even if you have nothing else: creativity, determination, love/caring, curiosity, passion, and resolve.
