You need to decide if you are writing this as if you are really in the position to do things or are merely describing what you might do. Check your use of tenses. Personally, I feel it would be more effective if you wrote it as if you can do something. For instance, the first sentence could read "As an influential member of the government, I am going to help parentless children to have better lives".
I also do not think you have included enough about the problems facing the orphans struggling to survive on the streets.
