Clarify your goals. Just choosing a vague goal at random won't work. Get specific about what makes you happy and what feels most natural to you. Keeping a journal for a few days or weeks will help you understand your inner self better.
Think about your goal until it becomes a quiet and natural part of you, like your DNA. This constant, laid-back persistence works a lot better than giving the universe a "hard-sell" about why you should achieve your goal. The goal you have chosen should become second nature to you as you instinctively pursue the path that leads to it.
Get out there and do it. Without action, creative visualization won't work. Take it one step at a time, one project at time, and always visualize a positive outcome. Creative visualization and positive thinking are inseparable.
Let new energy flow in. It might be hard to embrace the good that comes your way at first because it is so different from what has happened in the past. Remember to go with the flow and discard old habits. If you cling to old habits, you will sabotage yourself.
Detach. Distancing yourself from the outcome is the key to using creative visualization successfully. Never strain or worry about achieving your goal. If you encounter a setback, simply find a way around it.
