Conscious attention is a designed function of the brain
which scans the environment for any trouble making changes.
If you identify yourself with your trouble shooter, then naturally you define yourself as being in a perpetual state of anxiety.

You have heard that Christ said, 'My words are spirit and they are life'. So are my words spirit and life; they will burn their way into your brain and you will never get away from them!
Sometimes it's very hard to turn off my brain especially when I have an eighteen hour day. I try to stop working by 10 or 11pm but you know sometimes there is nothing I can do about it.

As human, we all have the same human potential, unless there is some sort of retarded brain function. The wonderful human brain is the source of our strength and the source of our future, provided we utilize it in the right direction. If we use the brilliant human mind in the wrong way, it is really a disaster.
There are three kinds of brains: One understands of itself, another can be taught to understand, and the third can neither understand to itself or be taught to understand.
