Who am I ?

Here is my message that I left in FB page 2 weeks before opening this store.↓

Im in eBay for 10 years with 3200 feedback and thousands of customers but I always dream that one day I will build an online shop of my own. eBay store is very busy and I can not take time to build up any thing so today I decide to close eBay store temporary and focus to my dream. I know that is crazy but if I dont do that Im still only an eBayer all time of my life. You will never be able to start up any thing without close something. I will come back soon with my online shop and hope that all of you will support me again.
