You need to be more flexible and innovative as a player.
Just because I don't give you all the strings doesn't mean there isn't more for you to do.

You want hospitals later, when your army and province are both bigger, and you have elites.
When you have almost nothing trained, low acres, and you're using mostly specialists, it's not as important to have them.

Focus on armories and banks first, while hitting and plundering for land and resources.
Once your army's really manly, you convert around completely, and prepare to destroy people.
