You have good taste. LOL.
I would recommend not aspiring to anything. Those motivations get lost to the wind at some point anyways.
Get to know the breed would be my advice. Often learning a sense of a breed, and why it has the type that it does gets lost in the enthusiasm. It is surprising how so many overlook this most elementary point.
If you truly admire and love the breed, rather than the idea of it, you will get to know it intimately. A knowledge that is more than a collection of facts.
The typical advice to purchase and use the Standard. Not to neglect the first part, which is your foundation. Memorize the standard for your breed. Get to know other breeds, especially breeds in the same class. Know how they were used, and why one might have an advantage over another in some respect. The breed's type both sets limitations, and enables them. The breeder determines whether or not they realize their potential.
If it is possible. Show your birds. Some may not know your breed as well as you, but you will surround yourself with experienced poultry breeders. Their practical experience and perspective is invaluable. Ask questions that you have been unable to resolve on your own. Other breeders will take you more seriously if you take it seriously.
Gather all you can, including a couple books on breeding poultry. The larger the paradigm, a broader perspective to draw from.
Learn what you can before you even source the birds. It is helpful to know what you are looking for, and why you might prefer one over the other. You could potentially save yourself a lot of time, moving forward. Once you have them. Roll up your sleeves, and go to work. It is one thing to read and talk about it. Another to do it. There are countless internet experts that have no practical experience, and therefore, no practical knowledge. Know who you are talking to. It doesn't mean they have nothing of value to offer. We just have to sift through it. Be careful not to dismiss it too easily. I have rejected ideas to have been convinced by them later.
Facilities before the birds. There is no joy in chasing our tails. Once it starts, it happens fast.
Bob's advice to start small, and slow, was wise. There are disadvantages to being small, but especially initially, there are more advantages. It takes some time to get a feel for them. There are enough NHs now, to pick up on some later if you need to.
Most of all, enjoy the birds. If they were not enjoyable, the rest means nothing. It is a hobby. Poultry people tend to be opinionated. You would think it was a religion at times. We can take it too seriously. It requires some passion to persevere. On the other hand, poultry people tend to be generous and good natured people. Even if it does not seam like it in internet posts, where a lot is not communicated.
Every spring, hope is renewed. It is an enjoyable hobby.
