According to humanistic psychology, the strongest desire in human psychology is the desire to be congruent with how we see ourselves, meaning that our self-image (how we perceive ourselves) aligns closely with our ideal self (who we want to be), leading to a sense of self-actualization and well-being.
In short this means you are whoever you believe yourself to be and your subconscious mind will find and create circumstances to validate that..
If you believe yourself to be a smoker, then its true.
If you believe yourself to be a loser, then its true.
If you believe yourself to be an unstoppable force, then its true.
Choose your beliefs carefully and guard your mind.
