I ran across this speech of Sen McCain and thought it the best I've read in a long time. I suggest you check it out. If that seems too hard, then read these two excerpts and reconsider.
I'm a conservative, and I believe it is a very healthy thing for Americans to be skeptical about the purposes and practices of public officials. We shouldn't expect too much from government -- nor should it expect too much from us. Self-reliance -- not foisting our responsibilities off on others -- is the ethic that made America great.and
If you find faults with our country, make it a better one. If you are disappointed with the mistakes of government, join its ranks and work to correct them. I hope more Americans would consider enlisting in our Armed Forces. I hope more would consider running for public office or working in federal, state and local governments. But there are many public causes where your service can make our country a stronger, better one than we inherited. Wherever there is a hungry child, a great cause exists. Where there is an illiterate adult, a great cause exists. Wherever there are people who are denied the basic rights of Man, a great cause exists. Wherever there is suffering, a great cause exists.
