Shakespeare

Hear my soul speak. Of the very instant that I saw you, Did my heart fly at your service

Sophocles

“One word frees us of all the weight and pain of life: that word is love.”

Kenji Miyazawa

“We must embrace pain and burn it as fuel for our journey.”

Lance Armstrong

“Pain is temporary. It may last a minute, or an hour, or a day, or a year, but eventually it will subside and something else will take its place. If I quit, however, it lasts forever.”

Jennifer Aniston

“The greater your capacity to love, the greater your capacity to feel the pain.”

Sophocles

“If you try to cure evil with evil
you will add more pain to your fate.”

Ludwig Van Beethoven

Never shall I forget the time I spent with you. 

Please continue to be my friend, as you will 

always find me yours.
 

Neil Gaiman

“Have you ever been in love? Horrible isn't it? It makes you so vulnerable. It opens your chest and it opens up your heart and it means that someone can get inside you and mess you up. You build up all these defenses, you build up a whole suit of armor, so that nothing can hurt you, then one stupid person, no different from any other stupid person, wanders into your stupid life...You give them a piece of you. They didn't ask for it. They did something dumb one day, like kiss you or smile at you, and then your life isn't your own anymore. Love takes hostages. It gets inside you. It eats you out and leaves you crying in the darkness, so simple a phrase like 'maybe we should be just friends' turns into a glass splinter working its way into your heart. It hurts. Not just in the imagination. Not just in the mind. It's a soul-hurt, a real gets-inside-you-and-rips-you-apart pain. I hate love.”
