Live a life that is best for everyone. The only other option is living a life that's best for you. Now, understand, I know it is appealing to act in your own self-interest...but what if your self is more than you thought it to be? What if you are actually one with your neighbor?.. Cause if this were the case, then acting in your little self interest really isn't in your true self interest.
If you are at all driven to be a good person, you need to slow down and take a serious look at the actions and thoughts existing as you. These judgments and emotions cloud and skew your perception, allowing a self-CONcept to believe that it is superior/inferior. STOP, with awareness of breath, then act in a way that is best for all.
It's simply the best way to achieve a world that is best for all...Heaven on earth! Done and done.
