Once you have a good income coming in pay yourself a Caesar salary. Do this only from Jan. to Nov. otherwise your favor rating will fall. I have done this during good cities and used the money to build up fast in lean cities. As long as you put your salary back down to normal in the month of Dec. you may ignore what your ratings advisor says during the rest of the year.
