While a spring is often simplified to a linear relationship between force and displacement as defined by Hooke’s Law, in reality, two different curves are created for tension and compression. The area bounded by these two curves is called the hysteresis loop and represents the energy losses of a cycle.
Life is like a spring. Some things in life change us forever. When we go back to where we were before, we may have lost something. However, if we refuse to move from where we are to avoid this risk, we gain nothing; we are simply a spring lying on a table
