Look at a flower, or nature for the matter. They don't grow loudly and draw attention to themselves. They take a while to grow, in silence, and bloom into a beautiful creation. This is the same with a vocation. Besides, the 7-8 years of intellectual formations, human formation and pastoral formation, one, in my opinion, must also have a quiet prayerful formation. One must grow in silence, with God. To pray and to grow in the Love of God.
