Others who don't create art do not understand what you do and therefor downplay its importance. Their lack of understanding is an issue they don't know they have to deal with, not you! You are blessed to have received the gift of expression and others DO understand, just not as many of them you hoped were part of society. Close friends and family is not a great indicator of the quality of people out in the world. It is what it is, focus on their good qualities and never have others play down your joy in creating art because you are living proof this is a thing that does not require their acceptance. Just be kind to one another, that's difficult enough :)

And for anything you do and achieve, there will be an increased group of "haters". Let them, they do not add anything. Add the love and focus on the mission ;)
