came across an article that i believe gives a good reason why some people cannot charge what they are really worth, here is part of it...
Consider this, you mind, your behavior, your beliefs they are all based on your "current reality" and your association with all your experiences in the past, but what you have to remember is your "current reality" is not the absolute truth it is only the "truth" as you see it. None of us really know reality as none of us are ALL knowing. So understanding this is the first step in releasing yourself and your mind from your limiting beliefs. You see most people set goals based on their "current reality" they only allow themselves to see an end result based on how they currently see ways to get there...this is very limiting and really holds you back from your true potential......
i think some people come from a working background that gave them the belief that they are only worth a set amount of money, they only earned £350 a week at bloggs factory so that is how much they are worth, but a professional who took early retirement and was earning £40k a year before sees his worth as that amount.
peoples previous reality is setting how much they believe they can earn, rather than them seeing a new reality.
