Changing society needs to start with ourselves the (first) 
Nowadays, many people complain about their situation/the situation in which that they live, their sufferings and the pain that they have/feel spent, those who do not have a job, those who are homeless, in the street, those who are sick and they do not find have money for buying medicineaments,....
All these problems and others pushs a lot of people to blame either the state, their familly and or society in general. But I think it’s so unfair to blame others and to make them guiltyies without talking about our mistakes, because as human beings, we are not perfect, we have also a side mistakes in our life. Therefore, changing society needs collaboration with by many/a lot of parts, the State, of course, as the first participant, famillies and ourselves as too. As Kennedy’s citation ’’ask not what your country can do for you, ask what you can do for your country". So if everyone thinks like this/in this way, (in that case,) we can build a strong society that it would be able to face all these problems without complaining.
