Breastfeeding for the first time to someone who never imagined doing it. Advice please?

I'm posting anonymously, I don't know if I'll get my post taken down. I'm sorry! 😬 I never imagined being able to breastfeed and I believe I might be able to. What advice would you give a first time mom who knows NOTHING about breastfeeding. I know it can be hard and I know baby may not but can you elaborate? I'm literally clueless! 😂 Please help.
