Beginner trying to talk with my Spanish-speaking family… what should I learn first?

I’m a total beginner in Spanish but I really want to be able to hold conversations with some of my family members who mostly speak Spanish. Right now I only know basic phrases and Pratika-type stuff, but when I actually try to talk I completely freeze 😅 If your goal was to have real conversations with family, what would you focus on learning first? Most useful phrases? Conversation starters? Common mistakes beginners make? I’d love any advice from people who’ve been through this. 🙏
