How do you know when God's talking?

Brittany • I ❤ my baby girl💖 my baby boy 💙 🥰🤰 God is always good 👌🛐 I got one on the way.

I know God has spoken to me before.

Lately I'm struggling with spiritual discernment though. I really want to go for a education and job but I'm unsure what to do. I have more than one opportunity. Prayers would be appreciated or friendly advice.
