I Love this quote to me it speaks to the essence of why we have a hard time with patience, a good majority of the time we want things to come and be on our timetable it is only when we choose to acknowledge that in truth we don't know the right timing of all things to benefit ourselves or other.

I believe once we can truly accept that everything does not have to happen how or when we do we can experience the world from the present now moment and allows us to enjoy where we are in this now moment.
