I've been crawling out of your allegorical cave since I was thrust into it at age 6 and this is what I have so far:

People understand passion and they understand fear. Practice speaking from the heart in front of a mirror about your passion and why Bitcoin. When you can't find the right words to describe something as you speak from the heart, realize that and accept it. That ignorance is what you need to solve and you can only discover the ignorance by admitting you don't know something.

How is your journey made possible?
Who contributed?
What is their legacy?
Why do they believe in it?
What does Bitcoin mean to you?

Only speak what you know. You don't KNOW the people you speak to yet, so don't force a decision on them. They will make the right decision for themselves when they are ready to.
