Virtue means doing the right thing, in relation to the right person, at the right time, to the right extent, in the right manner, and for the right purpose. Thus, to give money away is quite a simple task, but for the act to be virtuous, the donor must give to the right person, for the right purpose, in the right amount, in the right manner, and at the right time.
Where your talents and the needs of the world cross, therein lies your vocation. These two, your talents and the needs of the world, are the great wake up calls to your true vocation in life... to ignore this, is in some sense, is to lose your soul.
Since the things we do determine the character of life, no blessed person can become unhappy. For he will never do those things which are hateful and petty.
