You will know when you are of value to anyone when you are able to think about the person and feel good at the same time. When you love others without worry, you are an advantage to them. When you enjoy them, you help them. When you expect them to succeed, you help them. In other words, when you see them as your own Inner Being sees them, then and only then is your association with them to their advantage.Your thoughts can add goodwill or negativity to the situation. Choose wisely!
