It's thrown me into depression (as I'm not used to not being goal-based) and I'm kind of in a big existential limbo right now.
At this point, I'm realising that if there is no purpose in anything, don't live with purpose. Instead, focus on process, and action. Simply accept what is (observe reality), instead of imagining or striving for what isn't, and to me it seems a more logical and successful life, all previous things said.
Be more connected to reality. Simply, existentially focus on that. Reality is different to 'truth', in a way. Reality doesn't involve much thought, or actually any at all.
It's a mindfuck because I just gave a purpose or reason for living this way - but I've articulated the mechanism: don't live with purpose, just live with process. Just do, and yeah read some Eckhart Tolle. And Byron Katie.
And here's a thought: There's no point to anything, so you may as well feel love.
