Each friend you have offers you a different gift just by being who they are. The gift may be joy and laughter or perhaps they are the friend that makes you think or the one who shares adventures with you. But by having that person in your life it opens up new worlds never experienced before.
Be thankful for all the worlds your friends represent for you.
It seems to be human nature to focus on the negative things about ourselves instead of the positive!
Seems to me that joy is a much better feeling to focus on than negativity. There are times when I obsess on my health issues and it becomes my main focus. What if this or what if that? It is those times that I have to step back, have a talk with myself and focus on the positives in my life. That moves my energy away from the problems in a matter of seconds.
