you cant sell to yourself. its against rules and ur account can be blocked. you cant open multiple ids and trade between these ids. that too is against rules. selling is not easy anywhere. what ur selling should have some USP, real value for buyers to buy. also since u r new, prospective buyers will take some time to trust you before they start buying.
the way to go is to identify some item which sells well on ebay, check the lowest price and try to source the item cheaper and sell lower than that. it can give you initial push to launch you in ebay. needless to say that the item should be genuine, with warranty and should not be breaking any rules, laws of the land
best of luck
