Chris Howard writes in his article Program Yourself to Prosperity
“The reality that you accept is made up of a matrix of interacting belief systems that can either be useful to you or disempower you. Financial beliefs that can disempower you include convictions such as “It’s hard to make money,” “You have to be born into wealth,” or “You have to work for years to make real money as a sales professional.”
“If you accept these kinds of realities, it can absolutely prevent you from reaching your full potential.”
