I agree with the sentiment and that of grandparent. But I take issue with the notion of fulfillment. I think we ought to strive to do things that drain us. You can't fulfill yourself continuously. You can't learn if your head is full. We have this 'my heart if full' turn of phrase that makes the next sentence confusing, but you can't love if your heart is full (of things you hold on to).

Same thing with trying to leave a legacy, or trying to make an impact. If you decide some thing or another is a goal, with the best altruistic reasoning, you're still first choosing something to hold on to, and then putting effort into attaching more and more to that.

We need to perform life because we are living beings. We go through the acts of nourishment and socialization because we are at that stage, being people on Earth. But seeking any personally chosen result or goal is self delusion. Letting go of what I think is the right thing, and pouring myself into my life, as I interact with others and gain opportunities to listen to them, work alongside them, decide together what to do and do it. I am alive because the universe pours into me. I need to pour forth. That's how things flow through their natural progression.
