The Eurozone is suffering. All economic areas have up and downs. Being in a shared monerary union, you sacrifize some advantages for others: we compromise - I know, strange word.
We are building a stable, long term monetary union. We are learning, we are improving and we will have a strong currency going forward.
Next time another economy area is in distress, as it will unavoidably happen, remember about our crisis, and how we together saw it through.
Nowadays it is fashionable to attack the Euro. When the crisis is mastered, all know-it-alls will praise it. We do not need to care for the ones or the others. We do our thing.
And yes, the most practical consequence for induvidual citizens is that I do not care about currencies, at all. Except when I travel to Poland.
