Let us will against ourselves, for ourselves...

St Augustine in De Trinitate XIII, telling us what power we should wish for:

For whereas two things make a man blessed, as we have argued above, to will well, and to be able to do what one wills, people ought not to be so perverse, as has been noted in the same discussion, as that a man should choose from the two things which make him blessed, the being able to do what he wills, and should neglect to will what he ought; whereas he ought first to have a good will, but great power afterwards. Further, a good will must be purged from vices, by which if a man is overcome, he is in such wise overcome as that he wills evil; and then how will his will be still good?
It is to be wished, then, that power may now be given, but power against vices, to conquer which men do not wish to be powerful, while they wish to be so in order to conquer men; and why is this, unless that, being in truth conquered, they feignedly conquer, and are conquerors not in truth, but in opinion? Let a man will to be prudent, will to be strong, will to be temperate, will to be just; and that he may be able to have these things truly, let him certainly desire power, and seek to be powerful in himself, and (strange though it be) against himself for himself. But all the other things which he wills rightly, and yet is not able to have, as, for instance, immortality and true and full felicity, let him not cease to long for, and let him patiently expect.
