Peace. It is in the attempt.

It is a losing proposition to force yourself to peace. You may be disappointed in yourself that you are not 100% peaceful in all scenarios, with all people.  Your individual human nature must accept itself before you can resonate with another's human nature.  

It is a constant practice of self acceptance and others acceptance.  Know this.

Should the attempt at peace fail - know that it was in the attempt.

The acknowledgement of the attempt is the most important of all.
