Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom.
Viktor Emil Frankl M.D., Ph.D. (March 26, 1905 – September 2, 1997) was an Austrian neurologist and psychiatrist as well as a Holocaust survivor. His best-selling book, Man's Search for Meaning chronicles his experiences as a concentration camp inmate and describes his psychotherapeutic method of finding meaning in all forms of existence, even the most sordid ones, and thus a reason to continue living.
Everything can be taken from a man or a woman but one thing: the last of human freedoms to choose one's attitude in any given set of circumstances, to choose one's own way.
Viktor Frankl, Holocaust survivor
Liberated after three years of life in concentration camps, he wrote his world-famous book Man's Search for Meaning. In this book, he described the life of an ordinary concentration camp inmate from the objective perspective of a psychiatrist. (Viktor Frankl in Wikipedia)
