"I am not my atoms. You are not your molecules. We are part of the current moment of a billions-year-old lineage since the origin of life"

Ideas

1

You have to let go from your past views in order to learn something new.
Part of growing means accepting that you were previously wrong.

Often in physics, your professors tell you things that are known as facts of the world. But what they don't tell you is that many of those facts emerge from the human mind, where many past facts that were taught were in fact updated.

We often think of physics and other sciences as an autonomous thing that exists in the universe and tells us how it works. But in reality, all of these theories have been created by humans to help explain things that are regularities in our everyday experiences.

Much of our innovation and creation comes from the history of what we already know.
Our creativity and imagination were things that were once represented in our minds and on pages that we drew, like rockets and flying machines. And the existence of planes and rockets nowadays was in part casually created because we could've imagined them.

So there are some things in the universe that don't exist in the universe yet, but we can imagine them, and that may cause us to create them to exist in the future.

Then there are things that our minds are not yet capable of understanding or conceiving, where even the language we use may not be the right words to think about them.

People ask me how I make a successful career working on such hard problems. And I reply saying, it couldn't be otherwise.
To be fulfilled, you have to work about things you care about. And that's often more discipline, department and specific problem agnostic than we think.

Because if you don't work on something you really care about, then everything becomes hard. And if you work on something that's deep and meaningful, then nothing will stop you from working hard.
