Martin Luther King, Jr.: The Time Is Always Right To Do What Is Right

Our lives begin to end the day we become 

silent about things that matter.

Cowardice asks the question - is it safe?
Expediency asks the question - is it politic?
Vanity asks the question - is it popular?
But conscience asks the question - is it right?
And there comes a time when one must take a position
that is neither safe, nor politic, nor popular;
but one must take it because it is right.

The time is always right to do what is right. 

— Dr. Martin Luther King, Jr.
