You can do it! You can make the change you want...by changing what you focus on.
The old saying goes that "You become what you think about all day long"
Look around at your life, your circumstances, the way you feel. What have you focused on to create this?
Look for good things to focus on and maintain your focus. Persevere and you will see a change in what you feel and what you experience in life.
