Follow your passion. Nothing - not wealth, success, accolades or fame - is worth spending a lifetime doing things you don't enjoy.

Sometimes the sight of someone in one faith wrestling with that faith can empower you to wrestle with another faith. For me, it was reading about how the Catholic Church wrestled with itself in the 1960s. Pope John XXIII set Nostra Aetate - the Declaration on the Relation of the Church with Non-Christian Religions - in motion. It changed the relationship between Jews and Catholics. Today, Jews and Catholics meet as friends. If you can do that, after the longest history of hatred the world has known, that empowers you as a Jew or a Muslim to wrestle with your faith.
