text: You are on your way just by acknowledging that you are thinking negatively. Everytime you have a negative thought, catch yourself and turn it into a positive. Try to stop and think before you speak too so you have time to make sure that you don't speak negatively ideas as well. Have you read the book, "The Power of Positive Thinking"?  It is an older book but very good. I am sure it is in the library. Read some uplifting books. You will pick up on the positive lanquage and thoughts.  Good luck..you will be more upbeat in no time!
