Unfortunately, news isn't so good yet,

The reasons why some of us are skeptic is that almost 3 years after passed from this government's term, and we haven't seen much tangible stuff. We rushed to do our part of the deal, but from their side things are dragging, because of so many unresolved issues. Zarif & co were in meetings rooms until early morning, but they couldn't sort out these issues before signing and celebrating?
Let's not forget that the first concessions were made in the Joint Plan of Action which was signed in November, 2013.
I'd love to be proven wrong on with this agreement. I'm not a student or a scientist, I'm a businessman. Any economical benefits will make my life easier. But so far this foot dragging and uncertainty, and false hopes, has stalled the market. Iranians are smart. If they knew what's what, they could find the loopholes and get the businesses, like they were doing during all these decades of sanctions. But if you tell the business community, "sanctions are removed, hooray!" what will happen? They will wait. And they have been waiting, more or less, since 2013.
