I am going to make some very broad strokes here. So no armchair quarterbacking me. I know it's way more nuanced but I'm not writing an essay on Lemmy.

In general Western philosophies always have a "goal."

I know you said it was a broad stroke, and that in general is that way, but I kind of disagree still. I think Western philosophy is about finding if we have a purpose and what is it, and many philosophers since Greek antiquity to today have answered they are skeptic of it existing or it being able to be known. From Pyrrho of Elis and Hegesias of Cyrene to Arthur Schopenhauer and Slavoj Žižek.

The word we are looking for is teleology (not to be confused with theology). It refers to finality, that there is a goal. Many philosophers did not subscribe to a teolology.

Your human life is to prove your worthiness.

Same thing as before.

You need to look back and atone for your past mistakes. You need to look forward so you can do the right things to be worthy. It is very little about being in the now.

I agree a little more with this, there are many Western philosophers preoccupied with ethics. But that's why I think they were talking of different dimensions. It was not that existentially you should roam the past or future, that your mental activity should be there. It was about being responsible in the now for the future, and to be held accountable for your past. It was a morality thing, not a conscious/existential thing.

In this case tacos are the moment. So next time you're eating a delicious taco. Spend that moment to be one with your taco. Concentrate on the smell. Then feel the texture as you pick it up. How the various colors interact with each other. Then as you bite off some, feel the textures in your mouth and how the flavors interact. Watch yourself, be aware of every time you chew. Remember there is no past there's no future there is only tacos.

Hey! Go away with that mindful nonsense. If I do that, I spend too much time with a single bite and I cannot eat as much (/s).
