The Three of Wands is an odd card, as it is named Virtue, and I believe this often trips up those who are new to the Tarot. However, if you look at the Two of Wands and the Four of Wands you will see the Three falls neatly in between.
In the Two, you have reached a point where you control what you have built and you are looking for ways you can move forward. The Three gives you just that. It signifies a surge of power and growth. The Three can also signify honesty and integrity; other cards in the spread will guide you in this. All you need remember is that Fire means things are moving, things are changing. This can be in all aspects within a reading; but mainly in careers and ambition and personal drive.
