Implant your goals into your subconscious as if they have already been achieved.

If I want to be a confident person, continue to see yourself brimming with confidence in your creative imagination...see the goal already achieved and your inner mind will set producing your ideal end result.

Make a habit of refining your abilities through your imagination (walking into a room full of strangers or maybe making a difficult phone call).
Spend sometime doing it perfectly in your mind.
By disciplining your thoughts, you determine what you reap.

Focus on what we want.
Do not dwell on what you lost!
