In the laws governed by physics, gravity can only work downward. It is up to the body, to pull itself back up again. This law can also be applied to everyday life. Although life has a natural tendency to pull us down, we have to stay alive in the face of opposition. Our ability to get back up plays a key role in our potential to rise up again, against the forces of tension and gravity.
Vectors, relative to physics have a magnitude and a direction. Without direction, a quantity is merely just a scalar. Failure allows us to reassess our direction and magnitude toward a point, particular goal or outcome. Allow your failures to be your teachers. Never be afraid to fail.
