Prudence is the use of right reason to direct our actions. It identifies the way to get there. It identifies the golden mean between extremes. It commands virtuous actions like a charioteer. It includes deliberation (not acting rashly), judgment (not waiting for ever or using the wisdom of the world), and execution of the decision (which is aided by the other virtues, otherwise it's just a pretty intention).
We get there by:
1) Seeking advice
2) Knowing the purpose of life and how to get there
3) Deliberating decisions
4) Waiting for disruptive passions to subside.
