Suicide is man's way of telling God, 'You can't fire me - I quit.' Bill Maher
I think what we have seen in terms of gay teenagers committing suicide because of bullying is anguishing. I think young people, if they are feeling like they are confused, need to know that there are people to talk to and that there are places they can go and not feel alone. But I feel that they have just as many rights as I do to not be bullied. Kevin Spacey
Suicide is a permanent solution to a temporary problem. Phil Donahue
They tell us that suicide is the greatest piece of cowardice... that suicide is wrong; when it is quite obvious that there is nothing in the world to which every man has a more unassailable title than to his own life and person. Arthur Schopenhauer
There is no lonelier man in death, except the suicide, than that man who has lived many years with a good wife and then outlived her. If two people love each other there can be no happy end to it. Ernest Hemingway
