Just a thought;
A moment is just a point of time in one's life and within that realm all things change and are never constant - Like a river.
The coolest thing about a river is that it is never the same on a daily basis. How boring would life or a river be if it was exactly the same daily. The artery will ebb and flow with the conditions and change course through it's travel but one thing is for certain; The predominant path and goal, is the ocean. It always has been and will always be.
Man could take a lesson from this one.
