He who longs to lead a better life must not think that he cannot begin to live better
until he has changed the circumstances of his life.
Life can be and must be corrected not through external changes,
but through a change within, a change in the soul.
This can be done anywhere and at any time.
Only when such a change enters your soul that you are unable to continue your former life,
only then alter your mode of life,
but not when you think that you could reform yourself more easily by changing your mode of life.
— Leo Tolstoy
