I'm really tempted to say that marriage is the most difficult vocation to discern, because you can't do it by yourself. You have to discern with someone else.

But then I realized, you have to do that with every vocation. It's easier to recognize it in marriage, but every vocation is about a relationship. You and the Church. You and God.

So you can't figure out your vocation on your own. You can't just shut yourself off from God and the world and find some magical perfect fit path for your life all by yourself.

Discernment is a process of developing a relationship, and you can't do that by yourself.

I'm praying for you!
