You have to dream, you have to have a vision, and you have to set a goal for yourself that might even scare you a little because sometimes that seems far beyond your reach. Then I think you have to develop a kind of resistance to rejection, and to the disappointments that are sure to come your way. Gregory Peck

You may either win your peace or buy it: win it, by resistance to evil; buy it, by compromise with evil. John Ruskin

He wrote on subjects ranging from geology to architecture, myth to ornithology, literature to education, and botany to political economy.
And what country can preserve its liberties, if its rulers are not warned from time to time that [the] people preserve the spirit of resistance? Let them take arms…The tree of liberty must be refreshed from time to time, with the blood of patriots and tyrants.
— Thomas Jefferson, letter to Col. William S. Smith, 1787
