In connection with your dear husband, Shoghi Effendi would consider it in full and happy accord with the expressed desire of the Master that every man should have some permanent work. Much as he desires to see you both devote your entire energies to a well thought out, progressive and attractive presentation of the Cause - a thing he feels we lack lamentably - he would be very pleased to see your husband follow what the Master often repeated even to His own immediate family, namely the necessity of a profession. Of course you know that He always said His had been mat-making. (From a letter written on behalf of Shoghi Effendi to an individual believer, dated 20 September 1929; The Compilation of Compilations, vol. I, Arts and Crafts)
