The late congressman and civil rights leader from Michigan, is famously known for his phrase, "get in good trouble, necessary trouble".
A more complete version of the quote reads:
"Do not get lost in a sea of despair. Be hopeful, be optimistic. Our struggle is not the struggle of a day, a week, a month, or a year, it is the struggle of a lifetime. Never, ever be afraid to make some noise and get in good trouble, necessary trouble".
