“Sacrifice your current life for your new one” is such a north node / south node coded quote. 

South node will tell you what you’re sacrificing. 

North node will tell you what you’re sacrificing it for. 

There will be a feeling of discomfort that arises when you find out what that is because change is uncomfortable and doing something we’ve never done before is uncomfortable. 

Example: South node is currently in Virgo and north node is currently in Pisces. This may look like sacrificing certain worldly / material comforts in order to feel wealthier and more aligned spiritually, emotionally, and mentally.
