Good morning @tyme 

What a lovely question. Thanks for asking.

Personally, I didn't give it too much thought. I knew I was at risk of overthinking it (sometimes I do that 😋) so, I chose one of the first things that came in my mind.  I'm not French but I believe the French say Bon Courage to people when they embark on a journey. I guess I take it to mean "may you be courageous."
