To reduce risk it is necessary to avoid a portfolio whose securities are all highly correlated with each other. One hundred securities whose returns rise and fall in near unison afford little protection than the uncertain return of a single security. (Harry Markowitz)

The return from your work must be the satisfaction which that work brings you and the worlds need of that work. With this, life is heaven, or as near heaven as you can get. Without this with work which you despise, which bores you, and which the world does not need this life is hell.

W. E. B. Du Bois

Any community's arm of force - military, police, security - needs people in it who can do necessary evil, and yet not be made evil by it. To do only the necessary and no more. To constantly question the assumptions, to stop the slide into atrocity.

Lois McMaster Bujold

The chief end of our life is to live in communion with God. To this end the Son of God became incarnate, in order to return us to this divine communion, which was lost by the fall into sin. Through Jesus Christ, the Son of God, we enter into communion with the Father and thus attain our purpose.
