Apart from being the patron saint of green beer Patrick was wonderfully unlikely as a saint, and specially for the Irish. Behind his story is the crucial Christian teaching on the nature of greatness in a person. It is that being great is to do with realising what has been given to you, and then passing that gift on to those for whom it is next intended. It is not you that is great, but the treasure you carry. When you carry it well, like Patrick, you become a great carrier, and hence, in God’s eyes, great yourself.
I hope you might see what you have been given, and where, or to whom, you need to go with your received gift.
