You have to leave OPEC to worry about its own problems. We have a shared commitment to stabilize markets.

If prices persist above the level of 60 we will definitively take that into account.

Those arguing for a cut will have to defend their case and we will listen to each of them and reach a compromise.

I wake up in the morning and one thing that I worry about is maybe I may not have done my best for my people. I try always to do my very, very best and if I don't strive the hardest — this is what worries me.

I think that one of the problems that you're seeing here is the time commitment that you have to make to run for public office.

If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it's not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.
