We experience we exist right now ("I think therefore I am") but we'd like to make it more permanent than "just now." Convincing ourselves the world exists independently from us is an attempt at convincing ourselves that we exist independently from the world... a reciprocal push of the other into independence.
Fat chance: the world is the one we create, thus does not independently exist. Nor do we. What will you do today for a better world (hence for yourself too)?
