When I was 16 I started keeping a diary in which I recorded my disagreements with the famous philosophers. I didn't insist that they were wrong, that I was right and I had to prevail. I just agreed and disagreed with them. I thought there was a high degree of probability that I was right and some other thinkers were wrong. But I wasn't positive about it.

Strong feelings are fine; it's the overreactions that mess us up.

Convince yourself that worrying about many situations will make them worse rather than improve them.

You largely constructed your depression. It wasn't given to you. Therefore, you can deconstruct it.

Lack of forgiveness of others breeds lack of self-forgiveness.

We teach people that they upset themselves. We can't change the past, so we change how people are thinking, feeling and behaving today.

You mainly feel the way you think.
