Pay attention to your feelings and stay positive in all situations.
Energy responds to the energy that you emit. When you emit upset, negative energy then you attract more opportunities to be upset and negative. You emit thought forms and those thought forms respond to your energy.
When you run short of money, how should you react then? Should you be upset? Perhaps. Or perhaps you should feel happy because now you see you have a problem and you need to do something about it. Just being able to understand that you need to take action to improve your life should make you happy.
