My last piece of advice to them is that Bitcoin adoption starts with us, let's forget about the global side, how many people have you lectured about Bitcoin this year locally, I asked.
Many local efforts put together will slowly but effectively bring global adoption closer. The summary of OP's discuss is that we should focus more on the one we can do and how we can effectively bring the knowledge of bitcoins to people around us locally first before worrying about the global challenge. Except your environment does not encourage it, sharing the knowledge about bitcoins to people who need them should be our primary concern. You do not have to gather people into a room to teach them, if that is not possible for you, engaging in personal one on one interaction, can achieve a lot.
