Since mental toughness is high on my list, I loved when I heard the other day this quote from the movie, Edge of Tomorrow:
"There's no courage without fear."
And just ignore that this quote is spoken by Bill Paxton right before a lot of the future-soldiers are about to die from a future spaceship landing onto a beach infested with aliens. Okay - don't think about that part!
Seriously, anytime any of my friends get nervous or have anxiety, I remind them that those feelings just mean they care.
Let me say this another way - when your heart is racing, you are getting nervous, or you have anxiety, it means you care about something. And, that's not a bad thing. Right?
There's no courage without fear.
