Allah Almighty says that it is vital to change the internal condition of a person, after that their outer condition will be changed. There is an assumption by the people that changing the government can change the future of a state, this will not be possible and it is very much untrue. It can be correlated with the fact that you can change the government, but it will be of no use, if the inside of the body is suffering from diseases. If you have the love of girlfriend, cigarettes and Facebook in your heart more than the love of Almighty Allah, nothing will change.

First you have to conquer shirk, selfishness, greed, fear, hope, love and dependence on anything that is other than Almighty Allah. Develop the love of almighty Allah in your heart and learn about the religion Islam through a good Quran Tutor. There are some questions that you must ask from yourself which are. What is the thing that you love most?. Where you want to spend in your life?. Love of present world is the root cause of all diseases. 

Just like a corrupted heart can destroy the whole body, in a very similar fashion it can destroy the nations of people as well. This heart is very much filled with the love of world; it is very much poisoned by earning haram and looking at haram things. If the heart has a desire to have the latest mobile phone, to hang with friends, to talk with the opposite sex, smoking cigarettes and listening to music all the time, then this path will lead to the destruction of nation.
