Working inspires inspiration. Keep working. If you succeed, keep working. If you fail, keep working. If you are interested, keep working. If you are bored, keep working.

The American media produce a product of very poor quality. Its information is not reliable, it has too much chrome and glitz, its doors rattle, it breaks down almost immediately, and it's sold without warranty. It's flashy, but it's basically junk.

Although knowledge of how things work is sufficient to allow manipulation of nature, what humans really want to know is why things work. Children don't ask how the sky is blue. They ask why the sky is blue.

Life is wonderful. It's a gift to be alive, to see the sun and breathe the air. And there isn't really anything else.

And that's how things are. A day is like a whole life. You start out doing one thing, but end up doing something else, plan to run an errand, but never get there. . . .

In my view, our approach to global warming exemplifies everything that is wrong with our approach to the environment. We are basing our decisions on speculation, not evidence. Proponents are pressing their views with more PR than scientific data. Indeed, we have allowed the whole issue to be politicized-red vs blue, Republican vs Democrat. This is in my view absurd. Data aren't political. Data are data. Politics leads you in the direction of a belief. Data, if you follow them, lead you to truth.
