Dear Abuzar Ansari ,
Hello,
I think a new Seller has nothing to loose but has every thing to gain.
With every sale you will get encouragement to do better.
Just be sincere with your work & with your Buyers.
Give them the best of Quality & Service and there is nothing which can then stop you from being successful.
Just visit the listings of other Sellers who are selling similar Items and try to improve upon listing esthetics, Variety & Prices.
Try to be a leader in your category.
Do your best and more better ideas would automatically come to you.
