I remember being taught the Golden Rule when I was a child, however, I was not prepared for how it has changed my marriage, work, and relationships.
How did the Golden Rule change my life? Simple, I started treating others the way I wanted to be treated. Easy right? However, there were times where my ego got the better of me. Then I realized my ego just meant that I was Edging God Out.
Even in your business it is not about your profit margin, but doing unto others as you would have done to you. Trust God and leave all the consequences up to Him. If you help your competition then they will do the same for you. If they do not then leave those consequences up to God. It is not for you to control the situation. Or as Ram Dass said, we gain more control when we give it away.
If you are having fights in your marriage ask yourself if that is how you wish to be treated? Treat your spouse the way you want to be treated. It may take some time but eventually they will witness that your actions are not an act. They will know how much you love them by your deeds. What would you like to have in your life? It is your choice. Your spouse is not your enemy, because ultimately you both want the same things.
Practice this Golden Rule (Matthew 7:12) and see what happens.
