Positve Energy

I have been inundated with a wealth of information and cosmic hints about the power of positive energy and using your own positive vantage point to make a more pleasant path for yourself on this brief mortal journey. I tend to think that optimists do have a more positive life experience than pessimists; but is it because they are not allowing themselves to feel defeated and give up in the face of adversity or is there something more to the situation. Can it be possible that having a positive attitude and believing that positive experiences are always on the horizon actually attracts those situations to the individual? I would like to say this is true, but in reality both scenarios are equally likely and unlikely.
Whatever the cause may be, I am making a conscious decision to be a source of positive thoughts and energy. I am taking time to be appreciative for the blessings and positives in my life. Who could not be grateful for a loving husband, three intelligent, healthy children, a job that allows me to help others become successful, a steady income, a home, and the opportunity to explore my abilities as an author? I intend to give thanks for these elements of my life and many others on a daily basis.
To take this idea a bit further, I hope to surround myself with others who like me are positive and goal oriented people. Collaborating with others in my field can be the key to opening doors and learning new things.
Of course opportunities present themselves to us every day. Often we turn our back on the very opportunities we were hoping for because we do not allow ourselves to see the full potential of the situation. I am resolving not to let myself become left behind. To put it bluntly, when opportunity knocks I need to open the door and not sit idly by wasting perfectly good chances.
