Does every cent you spend contribute to your life? Or does money leak out of your pocket and you never have enough?
If you'd like to change your relationship with money, next time you think about buying something, ask "If I buy you, will you make me money?"'
Certainly a banana, or shoes, or a book may not bring a direct cash return (unless you're a fruit, shoe or bookshop owner). But what about their contribution to you in nutrition, style, information and feel good energy? Would that energy help you generate more money? Sure.
When you ask the question, pay attention to your senses. Do you feel light or heavy? If you feel heavy, then move on.
You always know if something will contribute to you or not. And how often do you ignore yourself?
