It's always interesting when people hear this concept for the first time. You can imagine telling somebody "you are as successful as you want to be." It gets a variety of responses.
You can accept this reality, as simple truth. Understanding that the tendency to react to such things negatively, is just the conscious mind trying to defend its reality. However on a subconscious level, you know that this is true. And now that you know this, you might wonder how to change your mind. How to accept this new reality and move beyond that glass ceiling. The key to success is to desensitize your subconscious mind to fear and failure, then condition it to accept higher levels of achievement. Plant the garden of your mind with seeds of happiness, prosperity and success.
