Preach it. Want it. PLEDGE IT TO YOURSELF.
With your hand on your heart:
"This week I will do X, Y, Z. This represents me, part of WHO I AM. I love and want this goal and I'm getting it done, taking a step every day THIS week."
Plan ahead to talk with someone each day and review the steps you've completed toward your goal. Any energy you put toward this will bring happiness to your heart and help form the real YOU.
