Affirmations are awesome. They can be powerful tools to help you push ahead in reaching your goals and objectives. But they are tools that must be used properly to be effective. A hammer does no one any good if it sits on a table in a back room, or if you pull it out when what you need is a screwdriver.
To reach your goals, there needs to be positive action, proper positioning, and a good bit of luck. Luck can be created by positive action and proper positioning, but luck is still luck. You will have to depend on some measure of randomness to make anything happen.
