Begin by looking around your immediate environment and gently noticing something that pleases you. Try to hold your attention on this pleasing object as you consider how wonderful, beautiful, or useful it is. And as you focus upon it longer, your positive feelings about it will increase.
Now, notice your improved feeling, and be appreciative of the way you feel. Then, once your good feeling is noticeably stronger than when you began, look around your environment and choose another pleasing object for your positive attention.
Make it your objective to choose objects of attention that easily evoke your appreciation, for this is not a process of finding something troubling and fixing it; this is a process of practising the higher vibrations. The longer you focus upon things that feel food to you, the easier it is for you to maintain those vibrational frequencies that feel good. And the more your maintain these good feeling frequencies, the more the Law of Attraction will deliver to you other thoughts, experiences, people and things that match your practised vibration.
