Yet another little gem of wisdom from

I know simple things. I know things that I have observed. I have observed many people make small changes if they try hard. I have seen this.

I do not know why. I know what. The what is: Most people can make small changes if they try.

And when do they try? Again, what I know and have experienced is this: People try to change when it hurts too much. They try to change when they have had enough pain.

But each of us seems to have a different and unknowable capacity for pain. Some of us will die before changing.
