Virtue is moral excellence. A virtue is a trait or quality that is deemed to be morally good and thus is valued as a foundation of principle and good moral being. Personal virtues are characteristics valued as promoting collective and individual greatness. In other words, it is a behavior that shows high moral standards. Doing what is right and avoiding what is wrong. The opposite of virtue is vice.
Virtue is when people realize their own limitedness, and let go of their pettiness in the infinity of the universe.
Virtues are the essence of our character and character does indeed determine destiny. The more we recognize the potential impact that practicing virtues can have on our lives, the more our lives open up to new possibilities and to greater joy and fulfillment.
