If we are not careful, we will let the energy from our past make us miss out on the future; that is why it is important to change negative habits and associates. When something is said or we find ourselves in a situation, we have to know that we have the solution. The solution is first, we can't change people or their views of us. We can control how we respond.
If you were on your way somewhere and someone said something about you that did't affect your destination and then you stopped in mid stride to respond, you might miss out on your blessing. For instance, you respond to this situation and you finally get to your destination. The Employer tells you that they were hiring for someone with your talent but they just gave the position away to someone who came there right before you did. Now, you just found out that you just missed out on a good job all because you responded to someone who had nothing to do with your destination. Time is too lightly.
