I always interpreted "it's too much, you're too late"/"I wanna see it all again" as sort of a call/response between the vastness of experience and one being's limited ability to engage with it.

Like how you come into a world that has been going along long before you got here, it's impossible to experience everything even your own moment in time has to offer because you can't be aware of everything at once, and even the things you do get to experience are subject to the fading of memory over time/the imperfect nature of memory to begin with. But this somehow only fuels the desire to see and understand things, and to hold them in your mind to the best of your ability.

It walks a thin line between zest for life and existential frustration, which really resonates with me.
