A colleague recently shared the toughness required to be published. Here's the story. If they say no to your art, try again. If they say No, try again. Try, and try and try. If you knock on the door, and it is shut in your face. Knock, again. Try the window. Try the chimney. If nothing is working, get an axe. Huff and puff. Do not give up.
I am sure if you quit trying, doors will not open to you. You must respect your work. Focus on emotional connection. This is what every creator is doing. Fuel your work with noble purpose and good. Avoid heavy handedness. Do you think the Universe owes you? Give up that stupidity. This is a big place, and the your life and times are less than a grain of sand and a tick of the clock (O, the insignificance). You are a tiny thing in a vast universe.
But, of course, you are here "to contribute a verse.' You are here to not "go gently into the night." Above all, "life is no crystal stair." Pour your words out like you have all the water in the world. Share your cup like it will never run dry, and send your positive vibes to all. The only thing that can trap your indomitable spirit is bowing down to the voices that say are not enough.
You have persistence. You have hope. You have "eternity in your heart". Jog on.
