Everyone you admire, everyone who’s accomplished greatness, faced obstacles along the way. Think about it. Everyone. The most impressive athletes, artists or public figures found their way to success by moving through and overcoming roadblocks.

Today, as my morning jog turned into a run and then a sprint, I felt my power and strength as a woman to keep pushing forward. No. Matter. What.

At the entrance to NASA’s Jet Propulsion Laboratory where I work, there’s a sign that says “Dare Mighty Things.” The way I see it, that sign is talking directly to me. “I dare you,” it says. Not to try something easy, but to run toward the challenge of climate change with confidence, strength and courage. And now I dare all of you.
