If for our own happiness we hurt others who are also pursuing happiness, we will not be able to gain serenity in the future. If we pursue our own happiness and do not hurt others who are also pursuing happiness, in the future, we will definitely receive the happiness that we have been seeking.
People should not step on the bodies of others to accomplish their own goals. In pursuit of happiness, people should not walk on top of the pain of others. In pursuit of abundance, people should not build their gains on the loss of others.
