I think the change is the most simple, I believe that changed themselves canchange others. If your friend is always let you down, you ask him, he will change? Have you ever thought of what time you make others disappointed?So, we have only one way to change others, this method, is to change our own. After the change of ideological system of our own, you will find that theyhave changed.
Complaining is totally useless. Blaming others will only be our own lost power,we keep some of our own strength. If we have no power, we don't have the ability to change. No ability to change, they will never find the way out.
