If you have only one smile in you, give it to the people you love.
-Maya Angelou
All anger is about something which has already happened. Is it of any use getting angry about something which you cannot alter?
It is wise to direct your anger towards problems -- not people; to focus your energies on answers -- not excuses.
-William Arthur Ward
One man can not wage a war alone. Therefore if humanity stops agreeing to go to war; there will be only peace.
-Richard Kevin Hartley
Declare it. Just the same way we declare war. That is how we will have peace... we just need to declare it.
-John Lennon
