"He that would make his own liberty secure, must guard even his enemy from oppression; for if he violates this duty, he establishes a precedent that will reach to himself."
--Thomas Paine

"The second half of a man's life is made up of nothing but the habits he has acquired during the first half."
--Fyodor Dostoevsky

"He who every morning plans the transaction of the day and follows out that plan, carries a thread that will guide him through the maze of the most busy life. But where no plan is laid, where the disposal of time is surrendered merely to the chance of incidence, chaos will soon reign."
--Victor Hugo
