The company you keep is not only all about the people; it is s all about the different senses and their objects. Like eyes crave to see forms. What forms you see is what company you keep. What sounds you decide to hear are the object of your ears. These are your food. Physical food creates your good or bad healthy body. Food (company) through senses creates good or bad mental states. Now you can decide for the day what food (company) you wish to have. That will decide your happiness today and in future too. Your good or bad company is deciding your future!
