John Stuart Mill as Project Manager

But as a Secretary conducting political correspondence, I could not issue an order, or express an opinion, without satisfying various persons very unlike myself, that the thing was fit to be done. I was thus in a good position for finding out by practice the mode of putting a thought which gives it easiest admittance into minds not prepared for it by habit; while I became practically conversant with the difficulties of moving bodies of men, the necessities of compromise, the art of sacrificing the non-essential to preserve the essential. I learnt how to obtain the best I could, when I could not obtain everything; instead of being indignant or dispirited because I could not have entirely my own way, to be pleased and encouraged when I could have the smallest part of it; and when even that could not be, to bear with complete equanimity the being overruled altogether. I have found, through life, these acquisitions to be of the greatest possible importance for personal happiness, and they are also a very necessary condition for enabling anyone, either as theorist or as practical man, to effect the greatest amount of good compatible with his opportunities.
