What's your "one thing"?

In one of my newsletters last month I asked, "What if you found that one thing that you go to sleep thinking about, that you dream about, that makes you leap out of bed with excitement and anticipation?"

That one thing that brings you into an unknown world full of new challenges? That one thing that will involve lots of learning and test you in ways you can't even anticipate? What's that one thing that might make you scared and nervous, but you still want to see where it takes you?

I'm grateful that I've found my one thing in UPPERCASE. I asked readers, "What's your one thing?"
