You already have a platform from which you can share your art.
You already have a kitchen from which you can make a meal that blesses someone.
Look around you and see you already have an audience. Hand them a plate of eggs and pancakes, or a printout of your latest essay.
Create a body of paintings and host an opening right out of your living room. Invite people that care about you. Invite people that will show up and bless them. Bless them with something they want. We all want food. We all want something created by someone we love.
