I spent an important part of my life participating in conflicts. But for me, conflict was not the main principle.

I will be engaging myself personally, as the head of the Polish government, in the optimization of conditions for the exploration, research, logistics and the business related to the production of shale gas.

Poles must understand history but we must also overcome it if it is obstructing our contemporary goals.

In Poland we still believe - and this certainly applies to my government - that greater competitiveness, and greater growth and savings are possible in an economy which is as sparely regulated as possible, where freedom, competition and private ownership are key values.

The misfortune of the wise is better than the prosperity of the fool.

Do I wish I had never endured postpartum depression? Absolutely. But to deny the experience is to deny who I am.

While I try and give as much energy, enthusiasm and detail to any work I do, if I keep coming back to it, to the same people year after year, there's an attachment. But you don't want anything to become comfortable.

You can and must always keep improving and working on your game - not just your weaknesses but also your strengths.
