Passion is what gets you through the hardest times that might otherwise make strong men weak, or make you give up.

You could be a poet, an artist, a comedian - if you're in the culture of innovation then you embrace those who do and you're going to protect the science curriculum in the classroom because you understand the meaning and the value of it. And science discoveries don't scare you. You say, "Give me more science", not less. "Give me more technology", not less.

In any case, the leading edge of our "on purpose" radio signals is 30 light-years away and, if intercepted, may mend the aliens' image of us based on the radio bubble of our television shows. But this will happen only if the aliens can somehow determine which type of signal comes closer to the truth of who we are, and what our cosmic identity deserves to be.

If humans one day become extinct from a catastrophic collision, there would be no greater tragedy in the history of life in the universe. Not because we lacked the brain power to protect ourselves but because we lacked the foresight. The dominant species that replaces us in post-apocalyptic Earth just might wonder, as they gaze upon our mounted skeletons in their natural history museums, why large headed Homo sapiens fared no better than the proverbially peabrained dinosaurs.
