Above all things, lose no occasion of exercising your dispositions to be grateful, to be generous, to be charitable, to be humane, to be true, just, firm, orderly, courageous, etc. Consider every act of this kind as an exercise which will strengthen your moral faculties and increase your worth.
Thomas JeffersonGive up money, give up fame, give up science, give the earth itself and all it contains rather than do an immoral act. And never suppose that in any possible situation, or under any circumstances, it is best for you to do a dishonorable thing, however slightly so it may appear to you.
Thomas Jefferson
