Look around you. Everything changes. Everything on this earth is in a continuous state of evolving, refining, improving, adapting, enhancingchanging. You were not put on this earth to remain stagnant.
The first time someone I loved left me behind..I didn't know how my family would balance. We had been such a sturdy little end table, four solid legs. I was sure we would now be off-kilter, always unstable. Until one day I looked more closely, and realized that we had simply become a stool.
In fantasy the world is always adapting to you, in reality you are always adapting to the world. That is the only difference.
Adapt to your surrounding but remain flexible for growing.
