Software engineer turned priest, perfect story for HN on Christmas Day, do tell!
My software skills still play a part in what I do. But seven or eight years ago now I felt drawn to explore a vocation in ordained ministry – after study, a formation programme, completing a Masters degree in Divinity, and a lot of thought and prayer, here I am. It's the happiest I've ever been. Which isn't to say that it hasn't been difficult: being a cleric is not easy work.
Intentional discernment about vocation really has made my life a lot happier, and it's something I talk about a little because it's of value to other people as well.
(I'm in the Anglican [in the states, Episcopalian] tradition, but the process of ministerial formation is very broadly similar between the various mainline protestant denominations and Roman Catholicism.)
