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.
