Meaning of You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete. :R. Buckminster Fuller
If we live our lives looking for the excitement and exhilaration that change can bring, we will be much happier than when we are eventually forced to accept it anyways.
Do the difficult things while they are easy and do the great things while they are small. A journey of a thousand miles must begin with a single step.
