Work hard for the money or.....

Now, I am focus in finish my studies achievement excellent grades. In seven years I can see myself working in the public administration. I would like to study a post degree for my specialization in the public policies or in the international area to get a chance to work in the Foreign Affairs Ministry.
My career is essential for my plans in the public sector, obviously I would like improve in my favorite area, this has relation with Political Science more than management in any Public Service . Also I think that: I can complement this aspect with other activities in the private sector, for example I would like have a clothe´s shop with my designs, I can have this activity as hobby or develop any economy activity compatible with my job.
I prefer to work in Santiago because old my life I live in this place and I wouldn´t like change my lifestyle because in other side of Chile I think what the lifestyle is more slow for me. If I can travel I would work as agent of Ministry in other country as Spain or Italy.
In the public sector the deal is equal for everyone, but In my ideal job is where I will work from 9am to 4pm and I can get a good income, not excessive but enough for I can have a quiet life without debts. I will get a job with a good relation with everyone (I hate rivalry or envy with the people! I have this hope). Also is very important to me can climb in the job, I wouldn´t like to be a person without improvement spirit.
