Start with the White Paper, configurate Nostr and 'x' accounts to follow top content of Austrian economics and Bitcoin (What is money show, Bitcoin University or The Path To Bitcoin) and subscribe to the Fountain App. Invest some time in reading stuff on Lyn Aldens homepage and start practicing the use of Lightning Wallets to get a feeling that BTC is alive.

I think the most important prerequisite for someone getting bitcoin is to start questioning “what is money”
Actually I will employ the rule “Begin with the End in Mind”. Non-Bitcoiners would likely be skeptical about this digital gold as they have heard a lot of bad press about it - drugs dealing, money laundering etc. So if they can be enlightened that Bitcoin helps address real-world needs, I believe their hard-liner attitude towards it will be softened.

Once they see that Bitcoin is a legit currency, I’m sure they will be inclined to find out more about it - even run their own node or whatsoever.
