Please do not carry this mental burden please, it may weigh you down and get you depressed when you feel you are underachieving. It is not a bad responsibility that you have given yourself, but that burden is not yours alone to carry, you alone cannot teach everyone about bitcoin because your resources are limited. It requires a collective effort from a community like this with everyone spreading the information to the people around them in their environment, that is the only way it will be effective.
It's okay to try to help, indeed - but not to burden yourself with much responsibility.
Because it's a process that is not mandatory for those involved, it's to help those in need.
