We all have an inner peace we can learn to consciously access. External rational thought creates external feelings. Internal conscious thought accesses internal feelings. Too much pressure causes stress. We need to learn how to control stress with more management classes.
Stress is caused by too much to do with too little time in which to do it.
The peace of God, which passes all understanding, will guard your hearts and your minds through Christ Jesus. I have learned in whatever state, I can be content. I know how to be abased, and I know how to abound. Everywhere and in all things I have learned both to be full and to be hungry, both to abound and to suffer. I can do all things through Christ who strengthens me.
