Overview
It's frustrating to be speaking the truth and still be doubted, but you must have the patience to wait for other people to come around to your way of thinking. Just stay consistent and make it clear that you respect what other people think (not matter how wrong it is). That way, when the people you love start to get an idea that you're on the right track, they can come to you without feeling like you'll give them any sort of 'I told you so' speech.
