If you wish to be good, first believe that you are bad.

until you have formed the habit of looking for the good instead of the bad there is in others, you will be neither successful nor happy.

If I say I’m happy, that means I was sad at some point. If I say he’s attractive, then somebody else is unattractive. Every positive thought even has a seed of a negative thought within it and vice versa, which is why a lot of greatness in life comes out of suffering. You have to view the negative before you can aspire to and appreciate the positive.

You must remain optimistic, for a negative outlook is more of a handicap than any physical injury.

Life is like photography. You need the negatives to develop.

In order to heal, it is essential to gather the strength to think negatively. Negative thinking is not a doleful, pessimistic view that masquerades as “realism.” Rather, it is a willingness to consider what is not working. What is not in balance? What have I ignored? What is my body saying no to? Without these questions, the stresses responsible for our lack of balance will remain hidden.

It's like a battery that has to have a positive and a negative. One doesn't work without the other. You've gotta have the good and the bad in order to know what's right, and in order to know what's real and what ain't.

Never make the negative the object of your study, because the negative is not there. You can go on and you will never arrive anywhere. Try to understand what light is, not darkness. Try to understand what life is, not death. Try to understand what love is, not hate.
If you go into hate you will never understand it, because hate is only the absence of love. So is darkness the absence of light.

we evolved to pay great attention to unpleasant experiences. This negativity bias overlooks good news, highlights bad news, and creates anxiety and pessimism.

Wanting positive experience is a negative experience; accepting negative experience is a
positive experience.

Maybe you have to know the darkness before you can appreciate the light.

Anytime you have a negative feeling toward anyone, you’re living in an illusion. There’s something seriously wrong with you. You’re not seeing reality. Something inside of you has to change. But what do we generally do when we have a negative feeling? “He is to blame, she is to blame. She’s got to change.” No! The world’s all right. The one who has to change is you.

Maybe you have to know the darkness before you can appreciate the light,” I

To think in terms of either pessimism or optimism oversimplifies the truth. The problem is to see reality as it is.
