That human behavior is more influenced by things outside of us than inside. The 'situation' is the external environment. The inner environment is genes, moral history, religious training. Philip Zimbardo
It is not the end of the physical body that should worry us. Rather, our concern must be to live while we're alive - to release our inner selves from the spiritual death that comes with living behind a facade designed to conform to external definitions of who and what we are. Elisabeth Kubler-Ross
There is something sublime about its aloofness from and its indifference to its external environment. Frederick Soddy
Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything - all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important. Steve Jobs
Genuine beginnings begin within us, even when they are brought to our attention by external opportunities. William Throsby Bridges
