Be careful what you think about! No, not because the #NSA or other Secret Service Agencies can suddenly read your mind (I am sure, they ARE working on it), but because YOUR thoughts ultimately create the results you are getting.
If you'd like to change certain things in your life, you need to change your thoughts. Your thoughts lead to feelings, those feelings lead to the actions you take (or inaction), and those actions lead to results. Change your thoughts, change your results.
