mm..

It is a tale. Told by an idiot, full of sound and fury, Signifying nothing. ...

We, as humans, do many things that seem to mean the world when we're doing them, but looking back, you eventually realise it was all meaningless.
People work and work for goals that they never wanted to achieve
They'll do almost anything because they are in love and want to make the love work, only to find when they finally have it, they were really in love with the process and the result is merely boring.
Humans are the worst kind of creatures.
