Please don't think you can start to make money selling domains until you learn the ropes. I would suggest you don't spend a penny until you have spent at least 6 months reading up. A few do it but most fall by the wayside.
You won't sell a bad domain for a good price. It's not going to happen so forget about.
Good advice for a newbie is to stick with dotcom. Why not try a niche you know something about ? Maybe you have a hobby or interest that you can test the water with. Your domain macaunightgirl is worth zero. Just delete it or let it drop.
Domaining is NOT a get rich scheme. Use the search on this forum to learn the ropes and good luck.
Best,
Paul
