Imagine you are 10 years into the future but this time it’s different. Why? Because starting today you actually begin making changes in your life. Specific intentional changes are not easy.

Joana Williams Oct 02, 2018

This is the path of a different choice, a different decision. You have the freedom to be how you want to be. Absorb all you need from this moment in your future and the positive things that you can learn consciously and unconsciously and then drift and float back to the place where the path splits.
