Decide what you want. Believe you can have it. Believe you deserve it and believe it's possible for you. And then close your eyes every day for several minutes, and visualize having what you already want, feeling the feelings of already having it. Come out of that and focus on what you're grateful for already, and really enjoy it. Then go into your day and release it to the Universe.
