Box of unknown size and origin.

Sometimes i wonder if this 'box' people speak of thinking outside off, is something that you could even get back into... would you be close enough to hear and appreciate your thoughts again? or is the comfort of the parameters in the curiosity of the external world... how big is this 'box'? have i outgrown it, simply by 'thinking outside' of it? am i still in the 'box'?
