Daniel Goldstein discusses the conflict between our present and future selves in his TED Talk. He explains that our future selves are focused on long-term goals and discipline, while our present selves seek immediate gratification. This creates an "unequal fight" that can be addressed through commitment devices that allow our future, rational selves to bind our present, irrational selves. Such tools help with self-discipline and make the future feel more real and balanced against temptation.
