The quest continues.

Is it really useless? To understand yourself?

Of course it's ego central. Your world revolves around yourself.

Usually. If you're average. The mode. The median. The mean.

But if you don't understand yourself, how can you understand other people?

What they feel? What they think?

Humans learn by experience.

Less by emotion, because emotion screws up experience. Nevertheless, emotion and experience.

Constantly changing. Self-discovery is about finding those patterns.

Finding those patterns in others.

There are 疯人, les fous, crazy people - who have twisted logic, but that is inevitable.

You are the only person you can control. So maybe it is important to learn how your gears turn.

…

By rotation inertia, D'OH.

Because if you can't control yourself, very likely you will not be able to even influence others. And because the product of mass  and the square of the radius  equals  circular momentum.

No one who solves the world's problems doesn't know who he or she is.

Albert Einstein knew he was a scientist. He had some pretty sophisticated sounding epigrams  he left us after his death.

"Science without religion is lame. Religion without science is blind."

"Anyone who has never made a mistake has never tried anything new."

He was pretty sure about who he was and what he thought when he discovered the photoelectric effect , winning himself the Nobel Prize in physics.

And perfect people. Who wants perfection? It seems wonderful to live in that kind of crap for a year. Or maybe a lifetime. The one thing that screws humans over when it comes to perfection.. is greed. Pride. Self-indulging things. We could study and become IQ300 mad scientists and, seriously, solve the world's problems. If we just stopped buying ice cream for a year, likely over half of Africa would stop dying from thirst. But no, we want to hang out with our friends. We want to date, Facebook, play sports, you know, eat ice cream. How much more useful are those than self-discovery? Ego is what makes us human, not perfect robots.

Robots, by the way, rust.

Like so. Fe(OH)3 => Fe2O3.nH2O
