I could not have said it any better than Irene did! :)
You deserve a pat on the back for taking the first step and finally listing your first item, good for you! I hope whatever the result of your first try is, it won't be the end of your selling career. If it doesn't turn out as you expected it don't fret and give-up but make it a challenge - learn from it and move on.
Now would be a good time to start checking out your options when it comes to products you might want to sell.
Jut sing out and we'll be more then happy to help you out!
