You can use your emotions as a guide to any decision you make in your life, from the most mundane to the most profound. If an option makes you feel badly, then it probably isn't the choice that serves your highest and greatest good. If, however, you feel joy when considering that option, then spread your arms wide and welcome it.
You embodied to live a life of joyful purpose. When you align with purpose, joy is always the end result. It really is that simple.
