The way our minds go about making decisions has a lot to do with the amount of pros and cons that have to do with that decision.
Like in the classic case of the cup, life can be full of light, or consumed with darkness. By measuring the volume of our lives we can assess the amount of inspiration we need in any given moment to make the right decision. Meaning we can use the basic concept of volume to get to know ourselves on a deeper level in the moment.
In the moment decision making might be intimidating at first, but like with any relationship, as you get to know the person it becomes easier to relate to them on the spot.
Hope our hearts can reach the maximum volume of love for the world around and inside of us.
