I don’t have just ONE favorite quote.  I do have several tattooed on my body:

Do or do not.  There is no try. –Yoda

I am one with the force and the force is with me–Chirrut Imwe

Always forward. –Luke Cage/Pops

Je suis preste –Jamie/Outlander

And some more…..

Honestly, I can have full conversations that are entirely worded with quotes and lyrics, so this is just the tip of the iceberg!!
