Here is great words of John F. Kennedy,
“Ask not what your country can do for you,
Ask what you can do for your country”
I myself I would like to change some part of the words which would be much for present situation.
Ask not what world can do for you,
Ask what you can do for this world and People who need Helps.
Personally I doubt United State of America, and Government all over the world. This is why I do not want to say what we can do for the country, – But I would like to say what we can do for the world, and people who needs helps.
