Thinking of getting a Hahn's macaw — talk me out of it (or into it)

I've been researching Amazon parrot for months and I think I'm ready. But I want honest opinions from actual owners. What do you wish you'd known before getting yours? What's the hardest part? What's the best part?

Oh my bird did this for about two to three weeks and I tried everything. Honestly, time was the biggest factor. They just grew out of it.

YES! This is exactly what I needed to read today. My parrotlet and I have been going through the same thing!
